I think 10x is achievable, given sufficient panic.
NOAA list 5x under heavy workload. Heavy workload is still controlled breathing,...'out of breath', rather than hyperventilating and/or severe CO2 hit.
Extracted / Interpolated From NOAA Diving Manual, 2001:
Work Level.............................. Typical Swim....Typical O2
Description__ _____RMV, lpm__ __Speed,Knots_ _Cons., Lpm__
Light..................... 22.5........ ...... 0.6............... 1.1
Moderate............... 40.0 ...............1.0............... 1.8
Moderately Heavy.... 62.5............... 1.2............... 2.5
Heavy.................... 75.0............... 1.4............... 3.0
Extremely Heavy...... 90.0............... 1.6 ...............3.5

From 'WHY US DIVERS DIED IN 1991' by Ben Davidson (SPUMS Journal Vol 25 No.2 1995):
...so, even erring on the moderate (and I do believe it is moderate)... how does that 'bullet-prood' gas-sharing plan deal with a 5x SAC rate increase?
Your table isn't really clear to me, and all I see is less than a 5x increase for any of the values on it. I doubt a 10x increase is even sustainable in a scuba environment for any length of time. Its just not realistic at this level of diving. If its 'realistic' for you and your team, somethin ain't right.
A 5x increase will debauch virtually any gas plan, RBs included. You done goofed if you're in the water with someone who doesn't have their act together at 250'. And if you're in the water with a person like that, I'd contend that YOUR sac rate is just as likely to go through the roof.
