"ideal set is 3x5 rep to 3x8 rep with 3 minute rest", ideal for what?
Ideal for hypertrophy? Strength? Power? Fat loss? Probably not endurance... Perhaps the exercise routines on this site aren't great (I don't know), if you have evidence to support your claims I would definitely be interested.

Small (3-8) sets for strength, bit longer ones for hypertrophy (10-12), but outside of specific extreme endurance training (e.g. long runners), training strength is often better than training endurance regarding to endurance tasks. You'll eventually do more regular PU if you train harder variations than if you simply increase PU volume. Strength work is also amazing for fat loss. Amongst other benefits, training for strength is much faster, and (in my very subjective experience) more psychologically rewarding.
Sources on this matter hard indeed scarce. I'm not saying those are just common knowledge, there are studies pointing toward what I said. I had access to those mostly during my biomechanics classes at University. But it's not amazing meta-analysis with double blind methodology and 3000 subject. Far from that. I'm open to change my mind when new (and better) studies will be released, but as the time of my studies, that's what you learn in universities
