It seems that there are a few different spots that people will randomly measure for draw weight.  I am referring to location on the riser.  If you are keeping at a 28" standard, are you going to the back of the riser, front of the riser, belly of the grip or is it just a style of the bow that justifies where to measure?

Thanks

26.25" from the deepest part of the grip to the string will get you the draw weight at 28".

If your riser is 1.75" deep, then 28" from the back of the riser to the string.  

To measure weight, I put on an old arrow with a piece of tape at 26.25" from the nock groove, then mark the deepest part of the grip on my arrow sheft....pull it to it hits the mark and take the measurment.

I measure from the front of the grip, same way I measure my draw length. If both numbers are "wrong", they are still right if you get my drift.
