I generally see it written as 25 "base hits" per 20 rolls, compared to a khopesh's 27 "base hits" per 20 rolls.
The logic is that (assuming you hit on a 2) you hit 19 times total. For a rapier/scimitar/falchion, on six of those hits you do a second base damage. That's six extras per 20 rolls, for a total of 19+6=25.
A khopesh hits 19 times, four of which do an extra x2 (compared to the x1 of regular hits, x3 is x2 extra) each for a total of eight extras, which works out to 19+8=27.
