What do the two available DayCountType values mean for NoteConversionMechanisms?

In context of https://github.com/Open-Cap-Table-Coalition/Open-Cap-Format-OCF/blob/v1.0.0-b1/docs/schema/types/conversion_mechanisms/NoteConversionMechanism.md

My understanding is that the field day_count_convention of type DayCountType is referencing how the interest_accrual_period is counted.

I think I know what the two values of DayCountType mean, but I'm looking for clarity as the documentation is light.

ACTUAL_365: This means to use calendar days / months. If interest_accrual_period is MONTHLY this would be on the same day of month as the date that accrual starts (or EOM if that date is not possible). If QUARTERLY then same rules but at 3 months, SEMI_ANNUAL at 6 months, ANNUAL on the anniversary. The "365" part of this really means "calendar" because if there's a leap day we're not expected to shift based on 365 are we?

30_360: I think this is clearer as it means to use 30 days for a "month" and 360 days for a "year" and anything in-between proportioned accordingly.

(I think we need to either improve the documentation, or perhaps consider adopting the approach we used for vesting with only allows MONTHS or DAYS for accrual and specifies rules re: day of month. This would more consistently support all possibilities, excluding a prior discussion of "business day" counting.)

Also needing clarification: what is ACTUAL_365? I have done some searching and have found the answers to be inconsistent. Then I found this reference which lists 3 different types of Actual/365

Maybe these methods aren't all relevant to our domain, but at a minimum we need to identify which one we mean.
