Best Max Strength Method??

i was thinking of this for the squat…2x5 (4 min rest between set)

start of using 75% of 1rm eg max 130kg in the squat…so 5 reps x 100kg then 2nd set would be 90% of the first 5 reps x 90kg add… 2.5 kg next workout… a week would look like…4 week cycle…
Week 1
MONDAY:100kgx5 90kg x5

FRIDAY:102.5kg x5 92.5kg

Week2
MONDAY:add on 2.5

FRIDAY:add on 2.5…

what are your thoughts on this…or are theyre more effective methods
