AOS and 2nd burn OK confirmed (21 seconds short)
Do you mean that the Briz-M propulsion cut off early?
I'd say it has to be the actual duration of a nominal burn. If you follow the successful Proton-M/Briz-M launches in recent years, you'll notice that the second Briz burn is almost always 20~21 seconds short.

"The BSS-702HP carries the xenon ion propulsion system (XIPS) for all on-orbit maneuvering."
Is this the first GEO sat with an all XIPS? That capability saved AEHF1 but a confirmation that this is the first to depend on it would be appreciated. Using AEHF as an example, the move to a GEO orbit will be lengthy--months. Is a schedule available somewhere?

Inmarsat-5 F1 is not all XIPS, it has still the usual bipropellant apogee engine. After insertion into GEO, it will use XIPS for on-orbit maneuvering.
