G100 vs 800XP/850XP/900XP/750: how the two fleets are really flown
On two of the three chapters' lead measures, the gap inside each fleet is bigger than the gap between the G100 and the 800XP/850XP/900XP/750. The clearest difference is flights a month: the middle G100 at 5, the middle 800XP/850XP/900XP/750 at 10.

Fatigue
On hours per landing, the gap between the types is smaller than the spread inside either fleet: the middle G100 at 1.5 : 1, the middle 800XP/850XP/900XP/750 at 1.4 : 1.
What each landing and pressurization cycle costs the structure: landings per hour and short hops.

Corrosion
Salt air, damp hours and freeze–thaw can’t be compared here: only 26 of the 51 G100s were placed on enough nights in the twelve months, and a comparison needs at least 30.
What the air around the fleet does overnight: salt, damp and freeze–thaw.
Engines and brakes
On hot, high takeoffs, the gap between the types is smaller than the spread inside either fleet: the middle 800XP/850XP/900XP/750 at 4%, the middle G100 at 2%.
What departures ask of engines, brakes and tires: heat and height, and runway length.

Departures we could assess: 51 G100s and 395 800XP/850XP/900XP/750s. Short-runway departures aren't compared: we don't have a sourced takeoff distance for every variant of the 800XP/850XP/900XP/750.| Measure | G100 median | Middle half | 800XP/850XP/900XP/750 median | Middle half |

G100 vs 800XP/850XP/900XP/750: on paper
Certified figures come from each type certificate data sheet, the rest from the manufacturer. Each figure names its source; a range covers the variants one page tracks together; a dash means we don’t have a source for that figure yet. We don’t have a manufacturer source for the G100 or the 800XP/850XP/900XP/750 yet, so its manufacturer rows show a dash.

G100 vs 800XP/850XP/900XP/750: questions
Which is flown more, the G100 or the 800XP/850XP/900XP/750?
The 800XP/850XP/900XP/750, by about 50 estimated hours a year: the middle 800XP/850XP/900XP/750 flew ≈157 h a year, the middle G100 ≈107 h. That is a fleet median: the middle half of 800XP/850XP/900XP/750s logged 95–262 h and of G100s 69–143 h, so one aircraft can sit far from its type. In flights, the medians are 5 a month for the G100 and 10 for the 800XP/850XP/900XP/750.
Which lands more often for its hours, the G100 or the 800XP/850XP/900XP/750?
The 800XP/850XP/900XP/750: its middle aircraft flies 1.4 hours per landing, against 1.5 for the G100, 0.1 hours fewer per landing. More landings per hour means more pressurization cycles for the same time in the air. Short hops, legs under 300 nm, make up 38% of the middle G100's legs and 40% of the middle 800XP/850XP/900XP/750's.
Which flies longer trips, the G100 or the 800XP/850XP/900XP/750?
The 800XP/850XP/900XP/750, by 1 nm on the median leg: 401 nm for the middle aircraft, against 400 nm for the G100. 41% of G100 legs and 43% of 800XP/850XP/900XP/750 legs were under 300 nm, a gap of 2 percentage points; 22% and 18% were over 900 nm.
