Hello Authors, The improvements in LEDBAT++ over LEDBAT look very promising esp. with regards to a LBE slow start and Multiplicative decrease. With regards to Multiplicative decrease, i.e. W += max( (GAIN - Constant * W * (delay/target - 1)), -W/2) ) I think GAIN in this formula is not necessary as it is a factor between 0 and 1 and doesn’t make much difference. I tried to re-write this formula to something like this: W -= min(Constant * W * (delay/target - 1)), W/2) ) Let me know what you think about it. A minor comment on the below text, I think it should be `the per RTT window when the delay ..` `In LEDBAT++, with multiplicative decrease, the per RTT window delay is higher than target is:` I plan to implement LEDBAT++ and will provide more feedback accordingly. Thanks, Vidhi
