Why are newbies pushed to science puzzles after section 4?

Any newbie moving this way may well look to a beginner puzzle - they may pick QTTN. But QTTN is covered in tute 5-1. This does not make sense - nor does it reflect well on foldit.

If there must be a push into the science puzzles prior to completing the tutes then move 6-2 into section 5 and 5-3/4 into section 6. Then push after 5 not 4. But push with a notification that uncompleted tutes remain.

Personally I think it is best that all tutes are completed first - but if there must be a break, can it be at a sensible point?
