Although I agree, if the ball is almost certainly not findable and if it is its unplayable why not hit the provisional, give a cursory glance for the original of maybe no more than 20 seconds. Move on if its not obviously visible.
In rough that deep you need the ball to be easily found to be able to play it with any authority.
If its not sitting pretty then you're not getting it out.
A quick look, if its not obvious move on and take the medicine.
Searching in knee high rough for a ball that you either won't find or can't play is a waste of time.
Even though I agree in principal and in bounce games I'll not bother having much of a search if it's in the jungle, if I'm in a medal going down the 17th with a good score, I'm going to have my full 5 mins. But even just having a quick look can soon start to add up if you had a group spraying the ball around off the tee.
several things are needed to speed up play and green keepers not being lazy and keeping the rough to an ankle deep length can definately help.
