I suppose I should be able to figure this out but some how it evades me.

Re: "step down tapers"

How many step downs would a leader have that uses a formula...10-8-6 ? ...seems to me it would be 3 but judging from what I've seen elsewhere it's referred to as 2 ?
And I see 3 step down referred to when there are 2 pegs on the right and 1 on the left [besides the end pegs ...that seems like 4 to me ????????
