But, since you’ve brought it up, aren’t we really interested in knowing when we have two or three low cards on the flop that are of benefit to us?

A second amateurish hack attempt at this...

3 low cards, not paired and not paring a hand card flop, making a protected low
1[(20/48)*(16/47)*(12/46)]=3.70%

3 low cards not themselves pair but pairing one hand card flop
3[(20/48)*(16/47)*(9/46)]=8.33%
1/3 of the time (2.78%) it pairs the 4, leaving you with an unprotected nut low. 2/3 of the time (5.56%) it is an unprotected second-nut low.

Three lows cards flop, pairing two hand cards {ex. 24T}
3[(20/48)*(9/47)*(6/46)]=3.12%

AQ42 flops three low split pair
1[9/48*6/47*3/36]=0.16%

This adds up to 15.31%. Buzz shows 15.30% for flopping three low ranks. The rest is probably my rounding error.
