New GNAS longbow classifications!

We are trying to encourage juniors into the sport are we not and this does NOTHING for younger juniors trying Longbow

Agreed this is something that needs sorting our as soon as possible.
I actually pulled out the tables and had an indepth look at them (using Excel)
One thing I noticed was the compound scores. If you look at a particular round as you change age group the scores stay the same but shift in position. Now this does make me wonder why something similar was not done for the longbow and barebow groups. I know the datasets are small but you could take the group/round with the most data to set levels, extrapolate up and down as appropriate, apply the same shifting method used for compound and use the remaining data to validate your results

I wonder if there is any chance of seeing the original data and spreadsheet calculation for the current compound,longbow and barebow classifications ? It would be interesting to see exactly how it was applied.

Sorry if I am taking this thread off the original topic

No m8, don't think it's off topic, i'd be happy to see the data used for this as well

You are using 42lb longbow? Or 42lb recurve?

I suppose most of ladyes have less then 40lb bows... I would say - 30-35...

42lb Bickerstaff longbow, but just 26inch draw

[NobleKnight]

I use 55lb Bickerstaffe with cyllindric (not barrelled) poc 5\16 arrows, feathers 5" with little spin - and get ~260 at York... What arrows\feathers do you use?
I am thinking about making barrelled set...

I also use 5\16 shafts, 3inch shield feathers and 100grain points for target
but 1\4 inch shaft, 1 3/4 inch dumpy feather and 60 grain points for clout.

I am also making a barrelled set of 5\16 shafts (going down to 1\4 inch for nocks) for clout testing.

53# Bickerstaffe. 5/16" rear tapered pine arrows, 100 grain points, 3" low profile feathers. Now referencing with first knuckle of bow hand on gold at 100 yards with my new bow, and that's improving as the bow settles... PB for a York last year was 319 (but that was with a different bow, same draw weight and bowyer though, and different arrows).

319 - wow! You are very close to MB

Rear tapered - did someone made them for you, or there is a way to make them by myself? I have seen a tаpering tool - but it was only for 11\32...

And do you glue the feathers straight or with spin?

I did try tapering the last few of an old set myself, if you search on here you will find advice and tips on doing this. This was a bit rough, but it did convince me it gave better sight marks. I now get my tapered shafts from Hi Force Arrows. Again, you should be able to find a link to them on the forum, if not then I'll post it in this thread. Highly recommended.

At the moment all my feathers are straight (as far as the materials and my skills allow!). I did have an indoor set for my lighter bow with 5" helical feathers on 11/32" POC shafts. They did really well for me. With my heavier Bickerstaffes I have tried a helical fletch indoors, but have had best results with 11/32" pine shafts, spined at 53#, with 160 grain piles and big 5" fletchings.
