I don't love going with 60% vs loose and/or aggressive opponents, I think it's too weak.
90% is fine vs tight opponents, I'd even go 100% in a lot of situations. For one, a player can be super loose preflop, but very weak postflop, and it can make sense to raise nearly every hand.
I don't like charts or generic strategy for any situation except readless strategy, and readless is only the first 2-10 hands in any given structure. So you really should only work on memorizing a specific range for 25bb if you play hyper, or 50/75bb if you play a different structure. It's rare that you're 15bb deep vs someone you know nothing about, or 35bb deep vs an unknown, etc. What you should learn is how different hands go up and down in value, their strengths and weaknesses as the stack sizes and opponent characteristics change. That will allow you to formulate a great strategy no matter what stack depth you're at.
