If it does it for full load, it'll sure give lower ripple @ less load
The decay's given by
-t/RC
V = Vp X e
Where t, give or take, is near .5 the peak spacing. So as RC gets bigger
the drop decreases to nothing.
And why if there's a near B+ short lotsa hum results. An often-missed
consequence leading to unneeded filter cap. change-out
