Are their exact HIs 24.0?

Yes - I’ve checked on WHSplatform and both are 24.0Are their exact HIs 24.0?

The bizarre thing is now I’ve looked other players also have the wrong 95%. I don’t see how rounding can be having an affect but could it be? I thought CH was a full number but is it a % behind the scenes?

25.2 CH 25 PH 23 - should be 24 (exact is 23.75)

14 CH 13 PH 13 - should be 12 (exact 12.35)

42.9 CH 43 PH 40 - should be 41 (exact 40.85)

13.9 CH 13 PH 13 - should be 12.3 (12.35 exact

What is the exact CR, Par and Slope?

If they are both 24.0 there is no way it is a rounding issue as the calculation is the same for both assuming they are both playing from the same tee sets on the same course. And are the same gender.Yes - I’ve checked on WHSplatform and both are 24.0

That’s my thinking too but I’m beginning to doubt myself _ especially as I emailed Club V1 to query it and they haven’t got back to me!If they are both 24.0 there is no way it is a rounding issue as the calculation is the same for both assuming they are both playing from the same tee sets on the same course.

CH is an exact number to several decimal places if there is another percentage to be taken off.Yes - I’ve checked on WHSplatform and both are 24.0

Did they both use the same method to enter the competition and their scores? eg HDID PSI, simple cards or the EG app .That’s my thinking too but I’m beginning to doubt myself _ especially as I emailed Club V1 to query it and they haven’t got back to me!

A thought. Was one a comp entry and the other general play?

No - they are both playing in the same comp and knowing them I’m pretty sure both booked in using their phones. Scores aren’t entered yet as the comp is tomorrow.Did they both use the same method to enter the competition and their scores? eg HDID PSI, simple cards or the EG app .

So the 4 extra PHs (not the identical ones that started my question) are likely to be different because the CH is likely to be xx.xxxCH is an exact number to several decimal places if there is another percentage to be taken off.

I have checked the examples you gave and the calculated playing handicaps were correct, so yes the CHs are xx.xxx which is the reason for the differences.So the 4 extra PHs (not the identical ones that started my question) are likely to be different because the CH is likely to be xx.xxx

I can guess at this one. Although their handicap indexes are both 24.0, this is a statistic calculated by avereraging 8 numbers and then rounding to 1 decimal place. They may be doing the averaging on the fly. I came across an anomoly like this in South Africa and they told me that they hold differentials in their database to (if I remember correctly) to 6 decimal places. But even just averaging the eight 1 decimal point differentials and then multiplying the unrounded average by .95 and then rounding the results to integers could produce the anomally.

If you post both players' best 8 differential, we could do a machine precision calculation to check that bit of it at least.

Steve’s 8 score differentials are 26.5, 20.5, 24.5, 26.5, 21.5, 26.5, 19.5 and 26.5If you post both players' best 8 differential, we could do a machine precision calculation to check that bit of it at least.

Cliff’s are 26.5, 21.5, 26.5, 19.5, 25.5, 20.5, 28.4 and 26.5

Steve 24.0 HI

Cliff 24.4 HI

Is this correct?

If so - should explain it all.

Oh, that's ruined the mystery of it all!Steve 24.0 HI

After speaking to our regional handicap advisor and to Club V1 it turns out that Club V1 isn’t always computing the correct PH until the player signs in….so although the system recognised that a players HI has changed it isn’t updating the PH - when one player signed in it still said his PH was 23 but the label that came out said 22! Our regional advisors club doesn’t use Club V1 so she spoke to another EG rep who does use that system and they had exactly the same issue - 24 of their players, off the same HI, had different PHs.

The advice was to send an email to members letting them know their PH may not be correct on the online booking sheet but should be on the label (should!).

Just why it cant do that for you is beyond me.....but then, I was only a programmer for 20 years before finding a better profession
