On what motivated the 2 [deg F] warmer request:

Two attachments: 15 day trends of
    (1) the FMCS temperature sensors vs. PCAL temperature sensors
    (2) the vertical positions of the SUS

The vertical positions of the SUS show a temperature overshoot (i.e. we corrected the too hot with too cool a set point), because the vertical position has been shooting up higher that before the upgrade (about 2/3rds of the way through the graph).

The PCAL temp sensors suggest that the XVEA was at 20.3 [deg C] = 68.54 [deg F] before the upgrade, and had settled to 19.3 [deg C] = 66.74 [deg F] with the recently set setpoint of 64 [deg] (which was a copy-and-paste from EY a few days ago). 

Hence, I requested a 68.54 - 66.74 = 2.16 ~~ 2 [deg F] increase in temperature.
