Well, that's certainly not good if it does not recognized the 'percentage' setting when allocating research but the problem is essentially the same for designing the AI research program. You need to space techs out and make a "gentle slope" of research costs so that the AI doesn't get bogged down in any one field for too long. If you think it's important for the AI to research weapons technology earlier then you can mod the files as you have done. I think that the AI also needs lots of resources to BUY all those spiffy ships, so I have bumped up 'infrastructure' techs in my personal mod.
