Hi Sam,
It seems Geoff may not be floating around this forum anymore. Let's hope he comes back to share his knowledge and experience on the airstill with us!
I'm pretty much with you. Just bought an airstill and fumbling my way through. First batch produced some great hand sanitiser! Now onto a Tomato Paste Wash (TPW) which is smelling much better, but let's see how it goes through the airstill. Planning a Weetbix wash next.
I think the spreadsheet is referring to an earlier comment in this thread. Look about 8 comments back - PDF link: "Airstill Brief SS.pdf". (not a spreadsheet as such).
There are other discussions I've stubbled across, although a little dated (hopefully timeless info!). Posting in case you haven't seen these:

viewtopic.php?f=7&t=1503I'm afraid I can't offer any pro tips, but good to know I'm not alone. Looking forward to sharing and chatting about the airstill.
Cheers,
