A couple things about bluffs...
1. What hands are you trying to get him off of?
2. Are you repping a better hand?
3. Can this player fold the hands you want him to?

Here, I don't think he's ever folding tp+, especially since all the draws missed, because he's so passive. Usually, it's way better to bluff tags who can read your line and might actually fold a decent one pair hand.

If you just want to get him off hands like 88 or A2cc, probably a smaller bet gets just as many folds.
