Talo, as I'm looking at the spread sheet, here is what i'm seeing on bench for example:
1 - 2 - 3 - 4
236 242 249 255

These are final sets of 5 with the corresponding weeks over top. So I'm reaching my "max" in the fourth week. 236 is roughly a drop of 13.5% of my max. So you slowly climb up to it. The numbers go up by 6-7lbs a week, so I'm close to anuj's 5lbs. But this is by percentage so thats the difference there.

If I were to drop my numbers 10% (as in your example) for each week, my final sets would look like this:

1 - 2 - 3 - 4 - 5
153 178 201 236 255

IMO those are just too drastic of a jump week to week. Going up by 30 or more lbs is going to wreak havoc on the cns, and IMO if your max is around 255, pushing 153 in your first week isnt going to do much for you.
