The old FSI engines were very optimistically rated for total n-sec from the entire life of their engines.
The old F100 actually tested out (when they and the E60 did not CATO) usually as a 100% E80 or 1% F80.
Most of their engines were nowhere near the actual advertised n-sec. I doubt the actual ISP was anywhere near 100 (especially if you were using their advertised numbers).
The old F7 was the closest to the actual advertised specs....it at least tested out as an F.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
