I just ordered a Mathews Prestige and write to ask if someone could run the numbers to calculate the speed I might expect with my setup using one of the computer programs. Here are the particulars from the Mathews Website: IBO=322 at 29" (30" unavailable for this bow), my draw length will be 28", and draw wt of 70lbs. My arrows will be 26" Easton Axis fletched with 4 blazers with a total wt of 385 grains. The brace ht is 6" and ltoff is 65%. I don't know what other numbers are needed. Thanks, andy

I have not run this on AA but just looking at the numbers you are 1" short on draw length so you will lose about 10 fps there and your arrow is 35 grains heavier than IBO which is 350 grs so that is another 11 or 12 fps loss. You will lose a couple fps for a peep, d-loop, nocking point, etc so lets guess a 3 fps loss. With what you have given I would guess you will get between 295 and 300 fps out of this bow as described. I spoke with a coupl guys at the Buckmaster last week that have the Prestige and they are raving about it. Hope you like it.

Presige

I ordered 2 days ago but I don't expect to have it for about 2 weeks. I'll let you know if I like it. I was shocked at the price, nit as you might think, but my dealer said he could get it for me for $769 + tax. i was expecting more so I'll see what happens when it arrives and if he misquoted the price.

Using TAP, your numbers and Mathews specs, I calculated 290fps for your setup. You should be within 3-5fps of that speed.

302 fps, just like Brian from GA says

OnTarget2! says 302 fps
assuming a d-loop,
peep sight
nocking point
etc.

The arrow is a bit on the weak side,
Easton Axis 400 cut at 26"
and with four 2" Blazers.


You can add an arrow wrap,
drop down to 85 grain broadheads instead of 100 grains,
and drop the draw weight to 68 lbs,
and then the arrow stiffness would be more appropriate,
and the estimated velocity = 300 fps


Mathews Prestige at 70 lbs DW
65% letoff
28" Draw Length


Easton Axis 400 shaft
Cut shaft to 26"
(not including the nock or insert length)

Use four 2-inch Blazer vanes
Use a full sheet arrow wrap (10 grains)

Use 85 grain broadheads

Assumes 15 grain peep sight
Assumes 7 grain d-loop
Assumes 7 grain tied nocking point
Assumes zero string silencers


Estimated Velocity = 300 fps
5.584 grains per lb of draw weight
FOC = 7.50%
75.80 lbs of kinetic energy
