Rep Continuum and Intensities

Hello Christian,

ive got a question concerning the rep continuum and the following example:

Bench press, 1 RM = 100kg
than i tested 70% 1 RM and got like 4-5 reps. (with enough rest)
4-5 reps are normaly within the range of relative strength.
So when i am using 70% here, im infact training relative strength??

Is that correct?
