To be honest, its not obvious to me, I apologise for my lack of understanding.
If you have the time, please can you explain why you'd expect a lower quality?
I can comprehend that there could be a quality penalty in if you change the
bitrate but I don't exactly know why that'd happen.

Leaving the quality aside, why would the overall bitrate be different? The
requested bitrate averages at 250k. Do you think the encoder rate controller
reacts to a bitrate increase quicker than a decrease? I'm not sure what is
going on here.

Thanks for your help.
