Iv put two of the same record on each deck and set them to 0% and I have to adjust them to keep them in sync
The problem is the "tolerance" of the electronic components that go into all electronic devices - your turntables included. Take a simple resistor. Buy 2 (or even 2 dozen) of the same value and measure them with the same meter. I bet you'll see to different values displayed. Next, use a different meter to measure the same resistors - I bet they display yet different values. You can do the same thing with 2 transistors, capacitors - you name it. It's not limited to just electronics, either.
Manufacturing processes have not managed to hit the 100% predictability mark yet. As a result, no two parts produced are exactly the same. No two loads of raw materials are the same - so it is going to be practically impossible for the finished output to be the same. Sure, they've come close - but I doubt we'll ever see the kind of similarity between supposed "identical" devices that you're looking to find.
You may find that "sweet spot" of pitch on 2, 3 or even 50 turntables where they play exactly in sync, but the indicator dials will not be in the same exact spot.
I hope this helps.
