Okay, I see.
Calling it a "rule" in your post seemed to suggest 10-in-24 was some sort of "optional" scheduling system that we have the choice to "practice" or not.
I'm sure you are aware it is in fact a Federal Law (FAR 91.1059 for "91K fractional operations" and FAR 135.267 for "on-demad jet-card flights") -- failure to honor it or abide by it in "practice" is illegal.
Hopefully you can appreciate my confusion on how you worded the question initially.
The answer is "YES" -- everyone (company schedulers and pilots alike) obeys the law and respects the 10-in-24 "rule" as it is written.
