[Elecraft] Need volunteers to try an even better version of KAT500 firmware (rev. 1.63) -- more accurate initial tunes

I updated to KAT500 1.63 and latest KPA500 and K3 firmware. I like the way 
the KAT500 follows the VFO on the K3 but I noticed something odd when the 
VFO is set near a boundary between two KAT500 stored band slice memories.

When RIT is enabled, the KAT500 follows the frequency set by the RIT 
offset. That is, I hear the relays click after crossing the memory 
boundary using RIT and stopping on a new listening frequency. If I press 
CLR to reset the RIT offset, the relays click again as the KAT500 follows
the VFO back to the original frequency and recalls the settings for that 
band slice.

However, When XIT is enabled, the KAT500 does not follow the frequency set 
by the XIT offset. That is, I hear no relay clicking after crossing the 
boundary using XIT and stopping on a new transmit frequency in the 
adjacent band slice, for which different settings are normally recalled.

Shouldn't it be the other way around, to optimize the match for the transmitter, not the receiver?

It's late, maybe I'm missing something.
