      I don't do any benchmark on any of my locos. But without any measurement I immediately know when of my loco runs smoothly or on the opposite jerky.
       
      -For example I've a batch of the first released AZL SD70s, those who run very slowly. I've read here and there that once put appart and reassembled again they run faster and with a lower current drive. Maybe. But as these run very smoothly and as I'm not looking for high speeds I don't need any intervention on these, as furthermore I don't experience any overheat on them nor on the power supply system.
       
      -I had once a stuck GP35, I guess after it swallowed a grain of ballast or any other rubbish. I sent it to my local hobby store for overhauling. After they charged me of the equivalent of $20 I recovered a loco that ran jerkily.... I just unscrewed a little bit the 4 screws holding half chassis together and everything came back fine (that lets me telling myself the next time such an event occurs I'll fix it myself....).

      Dan,
      Exactly. Manufacturer data would be nice. But also how do other people here bench mark their locos?
