Rule of 12

[Rooter]

Good idea in principle, but I have problems with it.

Not everybody's greens are the same speed.
Not everybody gets the same trajectory with the same club.
Not everybody plays balls that spin the same amount.
Very few chip shots are flat all the way to the hole.
Until I see it with my own eyes, I don't believe that a chip with a 9 iron will roll 50% more than the same shot with a PW.

Like I said, good idea, but don't use it on the first green in a medal and expect to chip it stone dead.
You need to play the shots with your swing and your​ clubs on your greens and take note of the results before you put it into practice.

Plus my mental arithmetic is not great, so i now need a calculator when green side! Great!

Can i use my iphone calculator in a comp?

Never heard of it until now but in my opinion it is over complicating things so not for me

Just watched the video on it, how complex can you make something so simple! Look at like this find a club that flies the same distance as it rolls ( now a 52 degree gap wedge for me) and that is a 1:1 or 50:roll 50 (easier not to round down) then look for the 25:75 club (8 iron now ) a 56 or 60 degree wedge would be 75:25 .. Now you know your distance %s you can play chips to elevated levels and bypass breaks etc you don't have to drop the ball 1 yard on all the time .
however the comment about the speed of the greens is valid as well, my club the greens are silly fast and I find my self using a 60degree wedge all the time, I am to frightened to using less loft because the ball just scoots on, plus every pin is on a down hill break ( yeah hard to believe but you can predict on medal day where every pin will be and I have only played 3 medals!)

you could also be chipping downgrain or into the grain. this will also affect the roll out!

What happens if you have a downpour halfway round and the greens soften up? Your gonna need about seven calculators and to take your bag with you to every inch of the course

Pelz distances on pitches. Yes - I know mine and they've been ingrained for years.

Rof12 calculations on chips

Aimpoint charts for putting

Seems a bit mechanical/robotic to me.

Nice to be informed of what happens - which I'd already observed anyway - but as chipping is a 'feel' shot, I'll give the calculations a miss and stick to my 'percentage carry/roll' style thanks.

.... as chipping is a 'feel' shot, I'll give the calculations a miss and stick to my 'percentage carry/roll' style thanks.

the calcs are effectively the same as the % carry roll; just presented in a different way - and I agree that for those comfortable with ratios and percentages (never underetimate how many people are not!) this is an over complication rather than simplification.

with regards to 'feel', experienced golfers effectively leave the mechanics of how to hit the ball on a chip such that it lands at spot X to their subconcious and call it 'feel' - fine. However, for many learning the game a few basic aides will help a lot.

my understanding from discussions with pro's is that they tend to use ratios, and they establish them on the practice chipping area for the greens and conditions of the day - any tuning required for rain during the round will be exactly the same as for putting (but generally a lot less than for those of us who play slower greens in the first place!).

once you have the confidence that, for example, your 7 iron is playing 1:6 it really is easy to make chipping 21 paces a matter of landing your 7 iron chip at a point 3 paces ahead of the ball, on the right line, and watching to see if it goes in...

I don't see this as any more mechanical than 140 yds to just short of the pin, no wind, no slope, hit a 7 iron - job done.

What about across....

 

[garyinderry]

haha. that has never crossed my mind. good point !

U need a short game lesson :rofl:

The rule of 12 is just a way of calculating your carry and roll ratios, so once you pick you spot (dependent upon lie, flag position, green topography etc) your club is picked for you.

It's not overly complex though it may seem it when first coming across it as anything new may. Googling it a Manzilla video comes up, some may have seen it and that explains it. They're arguing it's easier to hit a target closer to you than further away.

As you take from 12 the roll ratio.
The implication is 1:1 (50% for those that way inclined) => 12-1=11 iron.
1:2 (or 33-67%) => 12-2=10 iron (PW)
and it goes on so 3 parts roll is (12-3) a 9 iron, 4 parts roll is an 8 iron, 5 parts roll is a 7 iron... (not that complicated really)

Just as on a full shot or pitch where you know your clubs distance (hopefully) you then take into account wind, lie of the land, green firmness etc: so you apply this to the rule of 12: Green speed, uphill / downhill etc:, spin isn't huge in this basic chip shot and some people (like Pelz) argues spin can hurt chips as it's dependent on it's first bounce and can lead to inconsistency. Luke Donald is someone who commentators will often say how he uses trajectory rather than spin to control his shorter shots.

Homer Kelly said let mechanics produce and feel reproduce, Trevino said there is no such thing as natural touch. Touch is something you create by hitting millions of golf balls so practice and feel the shot.

This is just a way of choosing your club, some advocate using 1 club and getting used to manipulating that club, this may work for you. Some might like to fly it farther, some might like to spin it. As long as you can practice and do it it doesn't matter.

If you don't play or practice a lot this 'rule' may be beneficial. The less I play the more I'd use more clubs.

If you play a genuine chip shot, I think most people would be suprised how far the ball rolls.

If I want to practice this way of chipping (and yes practice can help you to get the most out of your game, and chipping is a shot that most people require several times a round). I go down to the practice area to a relatively flat spot, 12 (18 or 24) yards from the pin (nice and easy numbers to see the ratio). I then mark each yard with a different coloured tee peg. With 1 club I chip to each tee peg and observe the roll. I then repeat with other clubs mentally noting the roll. Then I play to different flags, uphill and downhill seeing the effects and what clubs I get the best results with in certain conditions (tier to go up, uphill, downhill) in soft conditions lobs can become more of a percentage shot for those who can guarantee good contact).

I probably don't do this in 1 session, but spending some time practicing your chipping isn't likely to do you any harm.

Cheers for information. Must say that anypractise I do this year will be more than last year so can only be a good thing. Have already improved my short game this with the help of a gps as I can measure different short shots and try to replicate the distances. I now have a few new stock shots, 40 yards, 55, 65, 90 and 100. Just need to find a few shot types to fill a few gaps and I will be happy.

These yardages are giving me confidence now inside a hundred yards as I can adapt from list if required until I cover most yardages from 100ish. Whereas before I didn't know what club or shot type to play I now know for example my 9iron with left arm to 9oclock will go about 100 yards, I can now swing more or less for a few extra yards.

Hopefully with a wee play around with the rule of 12 I can help my game closer to the green aswell.
