What is the difference in damage between 650 and 700 strength?

For a trained 5 slot pet with max base damage, what is the difference in melee damage between 650 and 700 strength?

I've asked around and noone seems to know the answer. Some told me that the strength bonus to damage only applies at 300, 500 and 700 strength. This means that a pet with 499 strength will do the same damage as a pet with 300 strength. I tried this out in TC and it seems to be correct *until* 500 strength, then it seems you get 1 damage bonus for every 50 strength. Not sure if this is the correct answer, but it's what I observed.
