Past experience on: Airplanes Spacecraft Nuclear Reactors
Just recently the 40kt barrier was broken by hydrofoil windsurfers. Fins still have a higher top end but the gap has been closing. I'm not sure what design change will enable foils to be just as fast or if they hit a wall.
I've personally done about 24kts on foil and similar on fin and in some cases it's a bit terrifying in more chop. Others are much faster than that.
I hear you on scheduling too. I've given best estimates and they then get chopped up and halved (or worse) by management types, then things start to slip and we end up being closer to what was originally estimated, but somehow everyone then gets surprised.
They are just robbing him
For instance, the engine no longer receiving oil at negative 1 g, or fuel, as the system is designed for gravity flow.
Stunt planes and airplanes capable of long inverted flight need special oiling and fuel systems to keep the engine from starving from either.
You can feel a much stronger pressure in the sail when moving towards the wind on a fast windsurfer/windfoil as you can do 15-20kts 45deg towards the wind, giving you an apparent wind that is 10-14kts stronger than the true wind.
On the same craft, going away/downwind, you will feel the apparent wind at a similar angle 10-14kts less. In fact, because of the change in drag and forces, you'll probably be going faster and feel even less wind on the downwind leg.
When you turn, this can be a big benefit for going downwind (jibing) as at some point the sail feels zero apparent wind (your motion cancelling out the true wind), feels very light in your hand, and easy to rotate to face the other way. Even knowing the physics of it, the timing and execution is still something that takes a lot of practice...especially on big race gear with a 9.0m2 sail.

I recently got gout when I really pushed my body hard by running 4x my normal distance in one week, still worked out, kept eating lots of junk (lots of sugary stuff), and drinking 3-4 drinks a night regularly. I also got a cold. Right after that, I got hit with massive toe pain on one foot.
Thankfully it was just a little bit of prednisone but it caused me to back off drinking and eat less sweet things. I'm relatively fit (~35" waist, 203-205ish pounds at 6'1"), but I also dropped down about 5 pounds (was about 208-210) after that and will probably continue to lose more.
Both 3rd and 4th amendment apply.
