The Radar refreshes every 30 seconds believe and the DNA scanner refreshes every 3 weeks I believe (I think it's based on proximity to the DNA target). These are both old values set from the very beginning from TTT. I don't think these slow refresh rates fit into the flow of the fast paced gameplay that modern TTT has, which is why I think they should be way faster.
I'd suggest that the Radar refresh rate was something like once every 12-15 seconds and the DNA scanner refresh rate was about 1/4 of what it is right now.
