A datalogger like an eagletree micropower can only measure with a capture rate of 1/10 of a second. If you use it with a lower capture rate you will miss some amp peaks you would have logged with the highest capture rate. My guess is that the esc measures with a higher capture rate then those of the loggers. And on the other hand ... a logger only sees what happens between Battery and ESC. Even if an ESC only draws 50A from your battery there could be much higher Amp spikes within the ESC. I think Patrick from castle mentioned this in the MMM thread.

It all comes down to: how you measure. At which rate you measure and where. This is why you see such different numbers when you compare the numbers shown in the MGMs software and those of an eagletree logger.
