It looks correct to me @Legend91x, it's because of when the breach is applied.
Assuming the enemy exec is max (192 speed) and your XB is184 speed:
When breach is applied to your RC both RC turn meters are at about 174/183, yours is 25% slower to fill the remainder of the TM bar for this turn; if you work it out, your RC's average speed until its first turn is ~180.2 (183 for most of it then 137 for the last bit after breach), i.e. slower than your executor.
(Your HT goes next because of the TM gain)
When your XB applies breach to their RC it is already at ~182/183; because its TM bar is almost full already, the speed down from breach has almost no effect on how long it takes until its first turn, it's average speed until it's first turn is 182.7. i.e. still faster than your executor.
