It's recommended as 9/8 * max(SRTT, latest_RTT).  So this means a packet sent more than 1/8 RTT prior to the current packet must be acknowledged.

I agree that RTT can be very noisy, but that tends to be from queueing/wifi/etc delays more than reordering.  If you have some data indicating reordering is substantially more common than the current draft can deal with, I'd be very interested.
