seems pretty subjective. I tried it out b/t classes at school and was getting 175ms on a good try and averaging around 205ms after 20 or so tries.

Tried it again now that I'm home and I can't break 275ms and haven't had a single one below 250ms.

Agree with Nuch. When I was at work I couldn't break 260, when I went home I pretty much hit 190-192 every time.
