Can anyone give me an educated guess of the speed on my new Defender?

I'm shooting 7595 GT's at 26.75" and 393.2 grains. The bow is 73# and 29" DL with the hush kit, string loop and a true peep. I'm shooting with a Scott LB goose release. I can't think of anything else that might be beeded for the calculation.

I won't have a chance to chrono it for a while.

Thanks
