SL/PE6 and MN/PE 2 questions

Hello, 

im still confused on what prescription is for SL/PE 6.  Workout calls for

"5x5r@".   Does this mean 5 reps or 5 on each side???  I know mastery is 5 on each side, but what does my prescription mean?

also, on MN/PE 2, I cannot touch the floor.   Should I put "cannot do any reps" or as many as I can complete in my 80%ROM??

thx in advance

For MN the reps count only if you touch the floor between the legs.

For the SL, the mastery it is 5 each side so basically it is 10 reps.
