First off you only have 500 hands of 1/2 which is a pretty small sample. However, regarding why you're running worse
at 1/2 with same VP$IP as before, I can think of several reasons why it's more costly at the higher limits.

1. Playing speculative hands out of position like small PP's and low suited connectors are more likely to get the additional limpers needed to be profitable. As the game gets tighter these mistakes become more costly.

2. Relative hand value is reduced. Similar to the first one, your questionable hands become unprofitable when your
opponents tighten up and play better hands.

3. More aggressive opponents. Those that isolate you and
make you pay more than one bet on these weak holdings are
now making you pay more to play these cards.

I agree that 27 is too high, for both limits in question.
