That is correct, and certainly the idea of loosening up is to
LEARN WHEN, because bluffing and playing marginal spots is not easy, that's the entire point of doing it now at 25NL when you're still learning. Playing weak-tight is not hard, and learning to play marginal spots is where your edge comes in.
You're right that in order to play marginal spots you need a good read... but that's what poker should be about! Making reads, using history to make decisions... in fact I would argue that to make default decisions without considering history and reads
isn't really poker*. It's just a robotic response that you can script. That is why I think once you've gotten a good grasp on "default" lines with hands, start considering your opponents, histories, and opportunities to bluff.
Don't use a "frequency" to bluff. Treat each decision as seperate, and don't be afraid. Say you had AA on the btn, you raiase, cbet, they fold. Cool. next hand, CO, you have 77, again you raise, they fold. This time on the HJ you get dealt KQs, so for the third time in a row, you raise, and they fold without a flop.
Now you're UTG, and suddenly you're dealt 67s. Do you go: hey, I've raised 3 hands in a row already, I should fold this?
NO! Each scenario is your own. If you can force your opponent to make mistakes by calling or playing back light at this situation, they make a mistake, and you profit! Raise that pretty, pretty hand up, and when they 3bet, and you know he's likely to be doing it wide or light, 4BET THAT FISH (or not, just a suggestion).
Also in my initial post I said '22 vpip" but I do realize that's a bit overkill. I think a vpip of 19-20 is loose enough to not make you a nit, but certainly there are lots of room for optimization. Check out these stats from the other thread:

Sexy right?
*obv it is poker, but you know what I mean when I say that.
