Uh I don't really like this at all. 150 hands is nothing when it comes to wtsd especially as he's nitty. You're looking at either 5 or 10 hands with him seeing a flop which is absolutely nothing. There's one maybe 2 fds in his range and 9 set combos. I can't see why everyones so anxious to stack off here with just one weird stat over a meaningless sample. Fwiw a we would expect a higher wtsd anyway because he's nitty preflop, and it could also be because of him being nitty postflop and not vbetting enough. Without seeing what he's shown down calling him a station is extremely dangerous.
