Snag and Night Wing, what type of bow do you plug into Stu's Calc. in place of a Blacktail? I've been using a Brackenbury. Is there a better choice?
Matbe we could get Stu to include Blacktails as a choice.

I would like for Stu to include a Blacktail in his (I hope for) next revision (upgrade) for his calculator.

I use "Generic Recurve" for the type of bow (Blacktail) I shoot. It's been spot on for me.

For your Brackenbury if it isn't listed, if it was me, I'd use "Generic Recurve" for a Brackenbury recurve.

Knowing the actual shelf cut-out dimensions may prove paramount.

idk if im not putting in all the right info but it sways my arrows underspined but my bare safts and broadheads say other wise. idk.

If you have a valid data point like that, tweak the personal form factor until the bow and arrows match --- then use that number in the future.

Hello Snag, and All,
I am truly humbled an encouraged by all your kind words! The DSC has come a long way from my personal spreadsheet I used when to trying to figure out how to make a good accurate wood arrow.  I have many improvements in mind and works and will continue to keep working on this with your help.  As an example, many have emailed saying the speed is too high for what they are seeing in their own chrono results.  This doesn't surprise me too much as the speed equation was originally developed using data from a shooting bench and mechanical release.  If your release is anywhere as bad as mine then you know we loose some speed for sure off the fingers.  Another factor is the effect of draw length.  Basically when all else is equal the longer power stroke will shoot faster than a bow at the same poundage but at a lower draw.  So, I have modified the speed prediction to know automatically compensate for both effects....I think you will find the results are much closer to "real world" shooting results now.  
Also, I finally figured out how to rightly handle tapered wood shafts so in the next release there will be a selectable option where you can enter the taper parameters and those will then also be compensated for in the predicted dynamic.

Bottom line is that many of you have helped and blessed me abundantly over the years and I will continue to pay that forward by helping anyone wherever possible.  Thank you again!
-Stu

Thanks for the info Stu. The calc. is very helpful.

Yeehaw, I got a maddog midsized longbow on the way and punched some numbers in stu's calc from arrows I have ready for hunting. Bow and arrow matched within .3 of each other. Man I hope its holds as true for me as it has for some of you all cause seasons close and I can't lose any arrow weight or add any of the arrow length back on.(LOL)

Thanks Stu
