Amazing, amazing, amazing! Did you watch Steve's game for tips to get that high a score? I'm in the 200k club but have a long way to go to get where your at. Congrats!
I think most people (myself included) would suggest you focus on increasing your skill and getting to higher levels over point pressing. Once you get a kill screen then point pressing would be the next thing to work on, but point pressing means taking extra risks, and not dying is too valuable to do that IMO.
But if it's more fun to you to point press than to get to a higher level and a higher score, then never mind.
