What percentage of your max do you use each week?

[snoboardr]

Back in college when lifting, our coach had us on a program using percentages of maxes. Something like:
Week 1: Find max
Week 2: do exercises at 65% max
Week 3: do exercises at 75% max
Week 4: do exercises at 80% max
Week 5: do exercises at 85% max
Week 6: do exercises at 90% max
Week 7: New max,
repeat
We had each week with something like:
Day 1: Upper body A
Day 2: Lower body A
Day 3: Cardio/Kinematics
Day 4: Upper body B
Day 5: Lower body B

Now, 10 years later, I am developing a workout app for mobile, and trying to make an algorithm to progressively lift more, and then remax, repeat.

I'm just pulling all of these numbers out of my head. It may be more like a 5 week program, or 20, I really forgot. Or maybe start at 70%. No clue.
Can someone please help me, what weeks should be at what percentages of max? Even better if there were different routines for females, weight loss, bodybuilding, general, etc.
