They were designed to be similar tunings at similar knob pointer settings, for familiarity 
and ease of use.

But smack on tuning is just a fluke. Like landing a thrown quarter on it's edge.

STAYING smack on tune over time and temperature is what is important, they do that 
extremely well, if they do not, tell me and I'll fix it.

Also I have had multiple reports that oscillators tuned 6 months ago are still in tune when 
power up again 6 months latter (after warmup of course).

There was a case where the system had been hit by lightning which completely blew out 
the powers supplies, the VCOs were running on unregulated +/-18.2 volts and they still 
stayed in tune and tracked a keyboard.

I don't recommend that though.
