Book incomplete. Data missing, i do not understand if vlaues are for sustained gs with or without suit. But its interesting...

Buy calculation of the formula sustained g-tolerance for 5.5g is 2.6 (seconds???). Multiply 1.3 for SACM then we 3 have seconds???

For Spinnetis maneuver 6gs:

14.08 * exp(-0.328*6)*1.3=2.6s. Do you pull it for how much time?
Not for very long, but I am not an expert in these things either. Honestly, other than making my arms and face really heavy, I didn't bother me...

Check this out:
http://en.wikipedia.org/wiki/G-force

Early experiments showed that untrained humans were able to tolerate 17 g eyeballs-in (compared to 12 g eyeballs-out) for several minutes without loss of consciousness or apparent long-term harm...John Stapp was subjected to 15 g for 0.6 second and a peak of 22 g during a 19 March 1954 rocket sled test. He would eventually survive a peak of more than 46 g, with more than 25 g for 1.1 sec.[6]
