New squat idea... again

Did some squats today and decided to do some high reps. I didn't feel mentally ready to test my maximum reps with BW, so I did the next best thing: A 10x10 set with 205, 8lbs more than my BW.

Front Squats
135x5
225x1

Back Squats
315x1
315x1
205x10
205x10
205x10
205x10
205x10
205x10
205x10
205x10
205x15(tried for 20, but wasn't there mentally)
205x5

This was by far the hardest squat workout to date. My heart was racing at set 3 and I was slightly dizzy after sets 3 and 4 and decided that I would give myself ample rest between sets. At least I will at first. I thought of yet another way to train for the 100 rep squat also. I will try to do this for the next few weeks, possibly months if I am capable and it turns out I make gains.

Do a 10x10 set but try to do a 20 rep squat after set 8. When I can get myself to do the 20 reps at the end of the squat session and do the session with less than 5 minutes between sets, I'll add 5lbs to the total and try to do the same. Once I feel I hit a wall weight-wise, I'll try to add reps to the last set instead of adding weight. I felt I hit a wall mentally on the 5th set because my last idea, to do 10x5, got me used to 50 reps, not 100. This will get me used to 100 reps and help me add weight.
