You should always go all the way to the stop. You should hear it thump every time you shift.

If you look at the pedal linkage and then the hydraulic advantage you will find that the throw out bearing is actually moving only a small amount when you push the pedal all the way to the floor - probably 1/4" or less.

It is possible that not going all the way to the floor could almost simulate shifting without the clutch - that process will definitely crunch, particularly so if you are shifting fast. I suspect that the high speed crunch problem is related to this as well - you may be trying to get it to the floor but everything is happening so fast that you may not be.
