I am not sure why this wouldn't work. I vaguely recall there was an issue
there, but can't figure it out staring at the code.
As this is quite ancient, I am not sure the JS part will even build anymore
:-/

You can change the default values at that line in the python
https://github.com/tardyp/buildbot_profiler/blob/master/buildbot_profiler/api.py#L193
I think you will be able to force them by editing this file inside your
virtualenv..
