This last point is important. Either it's high BDP and it uses the new stuff (and we WANT it to) or it's not high BDP and it USES RENO! That's why Baruch's email is totally illogical. If people don't have high BDP, these algorithms such as CUBIC and BIC change nothing compared to Reno, they purposely behave precisely the same.
