Well its apparently not close enough.
Last time I guessed (it turned out to be not too far off the average), I decided to use the DCS odometer in the AC6000 to actually measure it.
A lap is just shy of 1/2 a scale mile, so I'll just use .47 (It took about 3 extra feet to get the odo to reach .5 scale miles).
In 2 laps, there was a 30" gap between the 5V and the 3V, and a 15" gap between the 3V and PS3. A dash 9 is about 19", and an AC6000 is 20. So essentially the front of the 5V engine wound up 88" in front of the rear of the last engine. Basically, none of my engines are lashable, which is ridiculous.
Thats a 5.6% difference (front to front of rear engine).
Whether the 5V one is correct, who knows... I dont think it is. But the other two were the ones I had running together, and regardless of MTH's acceptable error range (the second two are technically 1.3% off), the stench of overheating electronics would seem to point at their acceptable range being too large.
So I suppose I could burn one of them up and send it back to MTH under warranty but that seems a rather extreme way to make a point to them, I'd rather just get them to work right (or better yet, they work right straight out of the box).
