Yes I understand it'll be different for different bows and different Indians, still it's useful info for me anyway.

I usually start at 12" but usually end up at 14-15"ish for my 60" bows.

I think I'm going to fiddle around with the distance today and see what I find.

There is a formula for placement I see used a lot.  3/4 and 2/3 of the distance from limb contact to nock point.  Can't remember which is top or bottom number.  I go by memory any more.
I have a great memory, but it is short.

Starting from top for a 56" string that would be 18.667" and 14", or vice versa.   I like 1/4ish of string length from string groove on both ends.

Trying something new to me.  Got an answer on the other site that 1/4 from top and 1/3 from bottom was professed to be best.  Shooting in the dark is a good test and it seems to work, but without a decibel meter we may never know.  Arrow flight with @745 grain Leopard wood was PDG.  Shooting in the dark between my privacy fence and house provides a good test tunnel, small thump which I hear about same time arrow hits target at 12-15 yards.

Four arrow group this evening.  Last arrow red nock tucked high right.  Light 2315 arrows flying well. Think it's tuned.

That's a good idea, going to take to wool off my string and give this a try.

Possum,
I've found it works as good as anything I've tried.  Price is right.

Will the madness never end?  Picked up another tip on the other site.  Suggested that putting silencers on L/6 and L/10.  "L" being the measurement from string touch points at the groove for longbows and on the limb curve for recurves.  The 1/3 and 3/4 helped quiet the bow and L/6 and L/10 brought back a bit of speed with equal or better quiet.
