MilDot, I think you only confirmed what most BowTech shooters are experiencing; in fact, while working the BowTech booth at the Illinois Deer Expo with Pat -- the man who handles most of the tech support for BowTech -- I asked him a question regarding the dots, and he basically said that too many people were putting too much stock in them... and he was going to suggest to have them removed for '07. I think he may have been kidding just a bit with that remark, as I know some people -- like yourself -- find them useful as a reference point. His premise was too many people were making too big a deal out of them.
Being that I shot dual cams up until 2000, I really never had any real problems keeping my dual cam bows in time except for a couple of high country bows, and I believe those problems were because of the string quality. The newer string materials available today do not stretch like the old fast flight strings.
Coug, if you can get your hands on a copy of the most recent issue of
Bowhunting World, there's a great sidebar on page 18 about "String Stretch & The Twin-Cam Bow." I'm gonna try to keep from re-typing a lot of it here, but if you need me to, I will. Some great points about twin cams and their offspring actually being less sucseptible to string stretch than single cams... especially with -- as you noted in your second post -- the advent of more quality strings.
Obviously, as Rick pointed out above, the binary cams are slaved together, which minimizes sychronization issues; you've still got to check for tuning issues, i.e., centershot, correct nock-point height, etc.
