Problem bots from Literumble

It could be. I'm running 1.7.4.2 Alpha2 at the moment as it accepts gzip/deflate encoded data for the rumble and helps cut down on my bandwidth. A lot of the earlier results are from 1.7.3.0 though, so it could be related.

Some quick tests show that DrussGT typically gets 80-85% on my 1.7.3.2 dev Robocode, so it seems the the results on Darkcanuck's server are a bit odd... I see in it's Tachikoma.properties file it is built for 1.7.3.2, but I don't think that could be giving it bad battles on 1.7.3.0.

Here is a more telling result: Tachikoma details sorted by date. Scroll down and keep an eye on the survival. Only the latest battles have any survival at all. The time they started getting survival corresponds with the time I switched my clients from 1.7.3.0 to 1.7.4.2_A2. So it seems it is a client issue.
