[RTTY] Contester preference - 1- versus 2-decimal-place spots

[Pete Smith N4ZR]

I'm doing some analysis of RTTY spots made by RBN nodes reporting 2 
decimal place frequencies.  Some of them I know to be using GPS 
disciplined oscillators, while others aren't.  The GPSDO stations 
generally agree within 10 Hz, and are probably better than that because 
of rounding errors.  The others are surprisingly good, almost always 
within the +/- 0.1 KHz we seek generally from RBN nodes.

My questions:  Do assisted RTTY contesters like to get 2-decimal spots?  
Or are they so used to 1-decimal spots that they automatically joggle 
tuning to get on the proper mark and space frequencies?

And... are inaccurate 2-decimal spots (still within +/-1-decimal 
tolerance) worse than 1-decimal, or essentially the same from an 
operational perspective?
