Hi Peter, this isn't about any specific setup. It's about a general failure to understand basic principles (e.g. averaged sampling, polynomial regression, and flawed reasoning regarding a single seeing affected HFR vs the entire autofocus measurement set). The developer has a fairly long focal ratio instrument (wide CFZ), so is less affected by poor final position than those with short focal ratios (narrow CFZ). As such, getting close was "good enough". Precision was never the goal. This is all-too-often a trademark of amateur / hobby development. All I can say is that it's fruitless to continue this discussion here in the forum. You (and others similarly affected) should send Jasem a PM if you feel strongly about having this finally fixed.
