It's not the size of the drop that matters... it's how it's shaped.

Size is part of how one defines shape.

Snark aside, you have a point. Nessie has an epic drop, but it is VERY short by today's standards. Apollo has a fantastic drop and it is not ginormous. i305 has a fantastic drop too, but it is quiet tall. (I like it because the feeling lasts so long) However, I think Griffon's is lame but it is similar in length to Apollo. Alpie has a drop, but it is lame. (IMO) DF had a decent length drop but it was lame.

The thing that I have noticed, and this is only if you are looking for constant feeling, drops with twists in them are not gut clenching like long straight drops. Nessie has some perfect mix that makes her drop wonderful.

I find 90 degree or more drops loose something.

I will quit pontificating now.

Yeah something about the 190 figure seems off. Like not a chance it's gonna reach 260 as that would go directly against the layout but I can see the drop landing around 200-205 (and would fit at the speed the train would travel over that top hat to reach 76 at the drop).

Bare minimum of 10mph, realistically either a bit more speed over the top or a bit more height to the drop.

Or maybe it's not really 76 after all. Shrug.

Storm Runner is said to go over at 10 and reach 72 at the bottom of the drop. Can’t see a 10 foot increase adding 4 mph

Also the 76 number is probably the most concrete number we have right now
 
You are misrepresenting how it was used. It was the last of three reasons that they tended to support the shorter height. And they highlighted their concerns with its veracity. Here is the exact quote:

“Lastly, though we have continuously been reluctant to rely too heavily on the leaked internal SEAS slide from last year, we can’t ignore the fact that a Rhine River drop height somewhere around 190′ matches very well with the top speed of 76 miles per hour listed on the BGW 2020 slide.”

So in danger of reigniting this debate, I've been doing some math on me own, and trying to reconcile some of the data, and I've come to 3 solutions to the data that is being speculated on:
1) 76 MPH was a target speed and not actually the speed this will reach. With a 159 foot top hat and a 190 foot drop, the top speed is really going to be about 70-72 MPH. This is assuming that when the train crests the top hat it's basically going to stall.

2) 76 MPH was a targets speed and is going to be the speed that this reaches. With a 159 foot top hat and a 190 foot drop. In this case the train is going to be cresting the hill will a decent amount of momentum. I'm not 100% certain of the cresting speed, but if my math is correct it's about 8-12 MPH.

3). 76 MPH was a target speed and is the speed that it's going to reach. Only in this case, they are still being vague with the height measures. This one takes a bit of geography trickery, so stick with me here:
The lowest elevation in BGW is at the bottom of the river, and is roughly about 20-35 feet below the river level (this is hard to know for sure as there could be sediment at the bottom changing the level). They could be using that elevation to play with these numbers a bit, and this changes the overall height of the spike, top hat, and drop length to fit the potential top speed some. If we use a rough estimation of 30 feet to the bottom of the river, that can push the spike to 209 feet, the topcoat to 189, and the drop to 220 feet. Those numbers relate well to a train barely cresting the top hat and hitting 76 MPH. I think this is the one option that we haven't thought of in terms of what these numbers could all be relating to.

I'm not certain if this will help. I'm in no way near being able to calculate variables as you. But it seems these examples achieve a higher speed with a lesser drop than you've calculated.

The bullet points for Parc Asterix conception-
First boost to top hat - 51mph
Stall
Backwards boost toward spike - 60mph
Stall
Forward boost to spike - 67mph
Stall at top of 147ft top hat
Initial dive speed- +/- 76mph

Soaring with Dragon first element is non-inverting loop at 187ft with spike at 197ft. Top speed down that first element is 78mph.
 
@GrandpaD a 76mph speed with very little boost takes a drop of roughly 225 feet. So unless there's some type of launch down or extra drop height we don't know about, Parc Asterix's top speed is a near impossibility.
 
I just pulled the numbers from the bullet points that appeared on the screen as the demo ran during the presentation. As I said, I have zero mathematic comprehension beyond grocery receipts.

Edit - @warfelg Would the fact the PA concept has a 131° drop versus the 95° of MMXX?
