Form 2210 forced dates skew reality

Two issues -

  1. The forced dates employed in form 2210 do not coincide with those in Form 2210AI as can be seen in the following images. 4/15 ≠ 3/31, 6/15 ≠ 5/31, 9/15 ≠ 8/31. I shudder to think about how the math is being performed below the surface.

  2. This issue is specific to Form 2210AI as shown in the image immediately above. For those who perform Roth conversions in December the form then forces a distribution that skews reality (Line 2 multiplier factors) that force significant portions of that exclusive December income as though it occurred in January when in fact, it did not. How "should" this situation be handled to reflect reality? I hope reality isn't too much to expect here.
