Sightmark estimator

[tel]

This seemed like the best place to put this - a tip worth its weight in golds!
Like the zombie I can be at 6 am I managed to leave home on Saturday morning without my sightmarks. After an initial panic I realised I had a printout from Linecutters estimator in my bag, albeit out-of-date. It was good enough to save the day - after sighters I had enough info. to translate the estimations into current settings and I have to say I was well impressed with the accuracy. Each time I change my set-up in anyway in the future I'm going to do an update and put it in my bag - I just know I may need it again!
Many thanks to Linecutter

Can you point me in the direction of that Estimator please? I'd like to see what it's like...

You can find it here under 'Other Useful Docs', as well as lots of other, well, er, useful docs

always carry a printout with me in my kitbag (and usually remember to update it fairly regularly too) - like you say its not 100% accurate but good enough to give a starting point for sighters

I was playing about at the club tonight & one of my (recently started archery) friends turned up. After winding him up a bit I persuaded him to join me at 50yds. Since he only had sight marks for 20 & 30 yds we used the sightmark estimator to give him a starting point. He then proceeded to bang all his arrows inside the blue.

Thanks that looks great and the initial calculations look like they're pretty close to the sight marks I have for a few distances I was unsure of!

Here's a small pic of the calibration chart:

And another to show how close it is to my real life sightmarks:

OpaNL,
I like the idea of a paper copy that can be taken to the field and used by anyone who needs it.

I found that I got the best results from the software when I entered longer distances(70m and 90m). but in general all of the marks it has generated have been fairly close.
