Latest version is overshooting

I upgraded the scream version to latest version and now it is overshooting. I always test this connecting a desktop client to an iphone client and simulating different bandwidth constraints in the iphone device with Network Link Conditioner.

With previous version (1-2 months ago old) it is never overshooting (even if estimation can be sometimes 100kbps below the configured bandwidth).

With the new version (today) it overshoots many times (f.e. simulating 200 kbps I'm getting 350-400 kbps constantly now).

I'm rolling back to the previous version but I'm reporting it just in case it helps.

PD. Maybe there is a new API or I should be using the new version in a different way, but I don't think it is the case.
