Apparently you disagree with Steve on the matter. The fumble tables though they might have overstated the severity, were based on his and other SCA participants in the process's observation of what actually happened in SCA combat. Which while not strictly "realistic" was probably not far off from the kinds of things that would happen in actual situations (they weren't also super far off from things I observed happen in various combat sports I participated in over time (the disintegrating fencing foil was pretty memorable).
I've fought SCA Heavy for a couple years and SCA Rapier for over a cumulative decade, and been a participating member of the SCA for decades, spending a lot of time at the field's edge (Herald and Marshal) when not fighting. Steve and Ray's fumble rules are WAY beyond the pale. People very rarely hit themselves. Not even newbs. Drop the fumble rules, and it's more realistic than D&D; with them, it's far less realistic than D&D.
Now, I have had Sir Kylson hit me instead of his target when I was serving as his shieldman. He was using a double-edge Glaive.
I've also encountered a lot of double kills in SCA heavy... but those aren't fumbles. Sir Phelan and I double killed 8 times in a row on a bearpit (He'd just taught me the Radnor Wrap)...
I've seen a number of athletic cups get damaged audibly, followed rapidly by the wearer exiting the field.
it's worth noting, however, that SCA combat in the early 70's was less efficient, had lower safety and training standards, and a lot less historicity.
I also knew a couple SCAers who knew Steve and Ray... the mutual acquaintances also felt the fumbles fun but unrealistic. And that ascribes the probable reason for them: [b\They're fun, not realistic.[/b]
the fumble rate in RQ is (5-(skill/20))%... which, for a typical dedicated fighter is 2%. The RQ2 rules (the earliest I've access to) specify 12 sec. So 50*12 =600 sec per fumble per person. That's 10 minutes.
30% lose future actions
20% strap failures . that's hourly - WAY too frequent. one to two orders of magnitude
5% fall down. Yup
8% twist ankle - I've seen this once - I slipped in the snow. (Yes, fencing in 12" of fresh powder.)
9% vision losses - doesn't happen in the SCA. mostly because of safety gear.
2% distracted
8% weapon dropped - 1 per 2 hours? under valued
4% Weapon damaged 1 per 4 hours? way too often
6% Hit friend
6% hit self - only had this happen twice; MoD/GMoF Nytshaed drove my dagger back into me on my failed parry. Never seen it happen on attacks.
Lose future rounds actions? A 12 second delay? You're hit before that.
Weapon damage? normally not seen on the field in SCA Heavy; normally, it's felt, and the weapon replaced. But this is rattan, not metal, and 1 per 40 hours to 1 per 80 hours. So... SCA Rapier? I've seen it rarely, never had it happen to me. SCA Cut and Thrust? 1 about every 100 hours. Usually on a parry, not an attack..
It's just WAY too often. And the lose next action is pretty much not happening in the SCA; The timing of the rounds is wrong.
It's also worth noting: Typical SCA 1-on-1 fights of the era did run 1/2 to 5 minutes for a duel... 5 min is 300 sec, or 25 rounds... with (from films) 1-2 min typical outside finals... but there are lulls... No game gets fights truly right.
