I just wonder what's the better way when we measure the peep to arrow.
Do we measure it from the edge of the peep to the edge part of the arrow or from the peep hole to the middle part of the arrow?

I hope this make any sense.

Thanks

The maths is done assuming the measurement is from the centre of the peep to the centre line of the arrow. However, this measurement is not critical.

Thanks for reply.

Bugger!! I have been exhausting myself while my wife trys in her ever patient way to get an accurate measurement... "It somewhere between 110mm and 111mm".

Meanwhile I am red in the face waiting for a definitive answer. :oops:

Measure it yourself Bigfella.

I sit on the floor with me feet on the riser and draw the bow with release in my left hand and measure it with my right :D

Just don't flinch or you could

A. Shoot your wife in the ankle

B. Cop a Riser in the nuts

Both are not good! :rofl:

I think that I choose going red in the face while waiting for a definitive measurement :oops: :oops: :oops:

Peep to arrow distance:
So long as you have that measurement within a few millimeters it will be just fine. It does not need to be extremely accurate. Any error here will simply shift the sight turnover distance slightly, which is not critical.

Errors in the peep to sight distance will simply result in an error in the calculated arrow velocity. That will very slightly change the settings calculated as it would calculate a slightly wrong arrow drag. However, the settings should still be very good indeed. hence, with 10 millimeters will be just fine.

The most important measurement to obtain accurately is the gap between the two settings. Any error there will change all of the calculated settings. For this one, I try to get right down to 1/10 millimeter (I use a micrometer to measure it).
