What is the forward CG limit in inches?

The forward CG limit is the furthest forward position the airplane’s center of gravity may be placed while still preserving enough elevator authority for safe rotation, control, and stall recovery. This limit is fixed and published in the aircraft’s POH/AFM, expressed as inches from the datum. Why 88.6 inches is correct: This value is the published forward limit for the aircraft. Staying at or behind this position ensures there’s still sufficient elevator effectiveness to rotate on takeoff and to regain control if a stall threat occurs. If the CG were positioned farther forward than this limit, elevator authority could be reduced to the point where rotation becomes difficult or impossible and stall-recovery performance could be compromised. The other numbers aren’t the published forward limit, so they aren’t the appropriate boundary to use for the forward limit. They may represent other limits or ranges shown in the manual, but the required forward boundary is 88.6 inches.
