Four EVLA antennas currently have Round Trip Phase monitoring:

ea14-l352
ea18-l352
ea24-l352
ea26-l352

Results (which are mixed):

14's slope is now correct.  26's slope is now inverted.  24 is still 
noisy, and none of the usual fixes was effective.  18 is just right.

The measurement from ea24 can be cleaned by a 10-minute (compared to the 
standard 10-second) moving average, and with such an average has 
long-term behavior comparable to that of 14 or 18.
