I noticed that when you run killer program, the progress is fast enough in the first one third, but then the speed drop significantly. Is this on purpose or something?

Also, it would be wonderful to have the bypasser always sold on Uplink ISS. I mean, you play non stop for 10 hours and eventually a bypass of v20 come up, alas you don't have the money to buy and have an appointment so you need to shutdown your game. By the time you next log in again, the Uplink ISS only sell v5 at most ==a

It was a failed experiment. The idea is that it spends the first third of the time analyzing the systems and the rest cracking it. Rather unbalanced.

I believe this has been mentioned time and time again, I think it is a bug. I think it should be fixed in the next release.
