I've just pushed a fix for this one. It's as simple as using the same mtu_time threshold for all tins.
This does mean that low-rate tins (such as Bulk) will be controlled to potentially unsustainably-low BDPs when competing against higher-rate tins. However, that will only affect goodput in the low-rate tins (and when ECN is not being used by the endpoints involved). I think that's an unavoidable tradeoff, and controlling latency is more important in this scenario.
