[Homeroast] Turning Bottomless Portafilter

I'm wondering if the more crema from a bottomless PF is caused by the lack
of agitation from hitting the bottom and the spouts.

Following that logic,  I'm wondering if the balance returns to the shot if
you stir the crema back in just before drinking?

Maybe it's time for me to get out the hacksaw and lop the bottom off one of
my spare PF's..
