Yep, I have it, but I don't have anything tuned around at the moment to check with it, and I don't use it for tuning, so I'd have to tune something aurally and measure. Also, I thought if I could get a few generous souls out there to supply a few quick numbers for me then I wouldn't have to figure it out myself. Besides, my point may have more credibility if someone elses data makes it. In any case, using Sanderson's formulas, a 50mm C-8 with #13 (0.031") wire at 4160cps will be at 150lb @ 62%. At 4245cps, it will be @155lb @64%, and at 4245cps, it will be @ 158lb @65%. That's with just the expected deviation from theoretical pitch to a ( I presume ) mildly stretched average tuning. Throw in some wild humidity fluctuations, and someone who stretches the last six notes a half semitone sharp of pure, and we begin to see what kind of over pull tolerance we're dealing with here. >Do the usual scaling programs try to accommodate any of the variations in >pitch that might be 'common' with a real world type tuning (stretch factor), >or do they just ignore that all together? Mine doesn't, but it's a heavily mutated version of a more straightforward scaling Excel worksheet that I was mercifully given to get me started without hurting myself. That being the case, I suppose I could add a stretch factor pretty easily, but it's not that big a deal. The numbers generated are close enough for scaling, unless of course you want to make an annoying point in group discussion. I don't know about other scaling software, but I suspect it's the same fixed pitch scale in them too. >(on a more personal note,...) >Glad to hear you had a good Thanksgiving. I did too.

Be that as it may, I'm happy to see you hanging in. Happy digestion, and thanks for the numbers. Regards, Ron N
