The four rule sets

Rule set	What it requires	Splits unlocked	Source
Standard rule everyone	Two periods totaling ≥ 10 h; each ≥ 2 h; one ≥ 7 consecutive h in the sleeper berth	7/3, 8/2 (and any mix meeting the floors)	49 CFR 395.1(g)(1)(ii)(A)–(C)
FSB pilot enrolled only	Two periods totaling ≥ 10 h; each ≥ 2 h; one ≥ 5 consecutive h in the berth	adds 6/4, 5/5	Docket FMCSA-2025-0193
McKee (MFT) USDOT #1025678 team drivers	Two periods totaling ≥ 10 h; each ≥ 2 h; no berth requirement	adds 6/4, 5/5	FMCSA-2014-0071 · Apr 20, 2025 – Apr 20, 2030
SDP pilot enrolled only	Split validity = standard rule. Separately: pause the 14-hour window ≤ 3 h/day of qualifying non-driving time (off duty, berth, on-duty at pickup/delivery)	— (window relief, not a split)	Docket FMCSA-2025-0194

Which splits pass, by rule set

Your pattern	Standard	FSB pilot	McKee (MFT)	Note
8/2 (8 berth + 2 off)	YES	YES	YES	Classic
7/3 (7 berth + 3 off)	YES	YES	YES	Classic
6/4	NO — needs 7 h berth	YES (5 h floor)	YES (2 h floor)	Pilot/exemption only
5/5	NO	YES	YES	Pilot/exemption only
7 off + 3 berth (no 7 h berth leg)	NO	NO — needs 5 h berth	YES	Check which leg is berth
7 berth + 2 off (= 9 h)	NO — under 10 h total	NO	NO	Total must reach 10

Always-true facts (any rule set)

Driving before + after the rests, added together: ≤ 11 h (MFT-covered drivers: ≤ 10 h by exemption terms).
The 14-hour window is recalculated from the end of the FIRST period; the two qualifying periods do not count against it (395.1(g)(1)(iii)).
Time between the periods (driving + on-duty) is what consumes the window.
Weekly 60/70-hour clocks are untouched by any split — and by the pilots.

Verify enrollment and current terms with FMCSA (fmcsa.dot.gov/regulations/hours-of-service) and your carrier before relying on any pilot or exemption row.
