I tend to do things my way, and in a manner that will best suite the route I am bolting.
Climb up, check out the hooking options, and scope how the free route will go, where the clip should be made etc..
Then come back down to the previous placement, get the hook ready, go back up and throw on the hook.
From there I test it low if possible, and then climb up and down on it to find the right place to stop and drill exactly where the bolt should be for the clip.
Never once messed up a route in this fashion.
Hard to put standards on an aid drilled placement. This "don't climb on aid past your hook" is retarded. You already lost the game, and now are doing your best for the route at that point where the hooks come out.
At a high standard, where hooks are your only hope in establishing the climb, you often have to throw the hook on without inspection/testing. Maybe that is what the OP was after in the original inquiry?
I figure it is like the dreaded rap bolting fear. Will this clip be where it needs to be? If not, you must hook multiple times to get where you need to be. Then you can take your feet and find the clipping stance, that thank god crimp and then you have affirmation that you are in the right spot, and start drilling.
Trying to put rules on hooking by means of "taking what you get" is not the best option for the route. I guess to each his own.
It's all cheating at that point.
