RE: How does the small c scenario affect the choke input?

There's small and there's very small. A 0.01 muF. part is used for kickback spike protection. A part less than 1 muF. is used as a "fudge factor" to adjust the rail voltage. At some point, critical current behavior will cease and cap. I/P filtration behavior will begin. What the exact value is has to be determined on a case by case basis. I'm very suspicious of both a cap. value greater than 0.47 muF. and an attempt to significantly raise the rail voltage above the RMS value being rectified. A volt or 2 above RMS might be OK.

The bottom line is that "breadboarding" and measuring, on the bench, can't be eschewed in favor of simulations.
