Guilty as charged.
However, when the timegrapher results are REALLY bad (whatever the lift angle that was - or wasn't used) you know there is something serious going on inside... I bought a couple of decent-looking watches on this forum whose movements were so battered that they required a lot more (cash injected in them) than the " basic service" they were advertised as being in need of. A timegrapher screen cap would have clearly shown crazy beat errors and totally inconsistent behaviours. Chances are I would have still purchased them anyway, but cheaper... and at least I would have braced for the final bill to get them to proper running condition.
Timegraphers screencaps aren't the alpha and the omega, but they are a decent proxy, which help define the "fine line between saying "the watch is in working condition and will need a service to get the best out of it" and "the watch is running; however it is losing 4 minutes a day, so a service is highly recommeded"".
