I can shed some light on the baselines. We don't start caring about how many transactions are happening until you've reached 40 transactions per second (to prevent baselining at no connections and erroneously blocking legitimate traffic). We won't take any action unless you have at least 200 transactions per second coming in, and we won't trigger unless the traffic coming in has increased by 500 transactions per second.
If you mean that you have IPs being blocked at 10 transactions per second, then I would recommend opening a case with support.
