No. Considering week one would be a max attempt of 100x5 it would go like this
Week 2: 105x5 PR because this is 5lbs more than I managed 1 week ago
Week 3: 110x5 PR again maintaining same rate of progress
Week 4: 115x5 PR progress is going well
Week 5: 120x4 not so good a sensible person here would deload as progress starts to drop off and you have been working near your max for a while
when it gets complicated is when week one is 100x5 and not so hard then by week 4 your doing 115x5 and its a real max attempt, this is when you realise you havnt quite been climbing at 5lbs per week and eventually it will catch up with you.
counting 90x6 after you did 100x5 the week before is retarded lol
