HI Bjorn, I just had this debate last week, no joke.. It got heated.. For me sit start means sitting and your bottom is the last part to leave the ground.
In most cases for FAs I try to do it with an ultra thin pad or no pad.
(to Gian: I am 168 and have no problem reaching the stating holds on dreamtime sit. My wife at 155 can as well and even place the heel. We have do pull on and then place the heel. For me in this case if you do not sit, it is not done, as pulling on and placing the heel is a hard move. It is just like dropping off a mantel that may not be the crux. )
This is for me the definition... OF sit start.
Having said that, It is silly for example to make a climb a sit if a crouch start is more logical, example fist hold is at 140cm and is a bucket with good feet. Now we are just trying to limit who can grab the first holds.
But this is also relative to stand starts with people stacking pads or stones, if the FA was done without them then the next ones should respect that. I can think of several problems where it is not the height of the hand holds, but the height of the foot holds that make a difference, and adding pads/stones can make a difference.
IN the end though this only matters for those who are "reporting" their results, for most mof us who are just there for fun who cares, just don't say Oh that was easy, downgrade the problem, when you could not even pull on the first move...
