These numbers are published in a number of places, but I used this document that appears to be pretty well accepted (I don't know who wrote it or when it was written, but it's pretty comprehensive). |
I recently watched a video by a fellow who followed this procedure. It's a two-part video – in part 1 you see him arc the leaves and in part 2 he re-assembles. Long story short, it's ineffective. He gets a higher arc on paper but the car sits the same as it did before he started.
I think it's hard to use this method, in part because the force is applied crudely and it's easy to underestimate how hard to pull, and in part because most guys won't have a known-good reference arc to aim at.
