What coaster has the strongest airtime, in terms of the actual level of force?

I've got no evidence, but have a vague recollection of DC Rivals bragging about having the strongest negative Gs in the final 2 hills during some marketing phase.

It didn't feel the strongest, though it's impossible to tell the numbers by feel anyway. I do say I felt airtime in my teeth on that bit, which remains a unique experience.
Oh, this reminds me... back when DC Rivals was in the testing phase, one of the engineers reported -2G's in the back row at the top of the non-inverting loop. At least, that was a rumor for around a week or two.

Seriously... is nobody going to mention SteVe? That thing has some of the strongest airtime I've ever felt. The double up into the MCBR, those ridiculous bunny hops at the end? Surely those are 'up there' in the premier league?
What about Taron? Those 2 twisted airtime hills are just absurdly powerful, they must pull some serious negative g's?
Storm Chaser? That's got some killer airtime hills on it too.
Blackpool's Wild Mouse? What were the figures like for that thing? I mean... I hated it, but the airtime on those drops bordered on violent.
Yep, clearly my top 10 should just be discussed;
Steel Vengeance / Lightning Rod / Skyrush / El Toro / Taron
Storm Chaser / Helix / Outlaw Run / Fury 325 / Goliath (GAm)


Maybe not Fury or Goliath, but every other one has at least one moment of WTF ejector, no idea which one has the strongest airtime though.

You mention violent airtime on the mouse, Magnum's ejector seat airtime was violently painful, so could also be up there.

So this raises an interesting (if un-answerable) question: at what point does 'strong ejector' become a 'bounce'? Mouse, Magnum, 'Nash, Bandit etc... - rides that tend to 'smash' you upwards into the restraint, rather than 'push' you upwards, is that still classed as 'airtime'? I mean... it should be, shouldn't it?
I seem to remember similar things being discussed in the Floater vs Ejector thread. I think it was @Hixee who made a good point about how it wasn't just about the strength of the G force, but more about the rate of change of the G force which determines what the airtime feels like. If we follow that logic a little further, we have to conclude that the truly strongest airtime out there is found on some of the roughest, bounciest old knackers in existence.

Bandit it is, then.

Wow, some of the stuff I say does actually get read! Who knew! :p

You're sort of right, in the sense that the rate-of-change of force plays a big part in how it feels, but that doesn't answer the thread's original question. All this rate of change stuff doesn't answer the question of which one has the highest (or lowest) absolute figure.

It's worth noting, however, that you have to do some intelligent thinking about this sort of thing. I can easily record accelerations of over +/-5G with my smartphone by shaking it (I did this sort of thing extensively during my final year thesis writing algorithms to process live acceleration data), but that shaking might not actually be fair to count. You'd have to have a minimum criteria for 'force sustained for at least 0.25s' type thing. That'd rule out all the bouncy stuff. Sorry mate, Bandit is probably out. ;)

force sustained for at least 0.25s
Hard to picture what that sort of timing is like on a ride. Wonder if that figure would rule out the little ones on the last diagonal of Balder. They always make me laugh with how short the bursts of airtime (and accompanying screams) are.

Alternatively, for the sake of the question, you could draw some sort of line between airtime created by design rather than forces exerted by unintentional violence.

Indeed, that's the question. 0.25s was plucked out of my head, but you could bring that down quite a bit I would have thought.

I was looking at the motion of boats during my thesis, so 0.25s was plenty enough of a filter to get rid of the vibration of the ship, dropped objects, influence of small buffeting waves, etc. I was only interested in the larger motion. For a coaster, you'd just have to bring that figure down a bit - I'd suggest just grab a plot and run a few different tests on the data to see what fits. Of course, there are plenty of off-the-shelf algorithms that do a more than just time sample and perform better, but that'd be a good start.

I imagine it would have been Dodonpa back in the day....But I'd have to give it to Skyrushes hill just over El Toro

Sorry if this seems like a random question, but on another airtime-related front, how accurate would the forces be on a GoPro force tracker, like the one used in this POV of Mako?:
