[Elecraft] K3 Autoinfo speed - different with USB?

[gt-i at gmx.net]

Hi all,
at the WinTest-reflector people asked why the K3 does not appear 
"smooth" in the band map as another vendor's TRX.
I made some tests and found out the following, see below.
Now my question: will the new USB-Interface change that timing behavior?

tnx, 73, Gernot DF5RF
