Ok, maybe a dumb question here, but how are you measuring key taps with that?
So the shortcut to start and stop is " - " (minus sign, ignoring the quotation marks). So what you do is reset it first, then quickly double tap " - " sign.
It will give you a time, but you have to reset it every time otherwise it will keep adding up to longer and longer time.

I get around the same result on Matias Quiet Pro (Dampened ALPS). Which is a pretty tactile switch. I should try it with a linear switch later.

There's no need to be argumentative about it. It's simple physics. If you want the key to activate twice, the fastest way to do it is to press to actuation, then release to reset, then press to actuation. The fastest way to do that is with a linear switch as long as you have good feedback from the system or know the switches really well (you can judge it by the force or relying on experience). If you're not used to where the actuation point is, a tactile (non-clicky) will be faster for you since you don't have to "guess" where the actuation or reset is. Clicky will be slowest, due to having to move the most between each change in state.
I hover when using movement keys in some situations where I need to change my position rapidly, so it's NOT "some random dreamup". Double tap is the same as hover, you know where the actuation point is and hover around that point (down, up, down).
You may not be sensitive enough to feel it, or unable to hover properly, but it doesn't mean it doesn't exist. I agree that MX switches weren't design with 2mm actuation to enable hovering, but it does make it possible.
^ This man speaks the truth.
It's simple physics, MX Brown and MX Red actuate and reset at around 50% mark, so theoretically you can lift the switch 60% up and press down again and it would work.
MX Blue actuate at around 50% and resets at around 75% up. So you'd have to almost lift the entire switch before being able to press it again.
Let alone that MX Brown and MX Red have 45g force and blue has 50g force and more noticeable bump, so it will take more effort to overcome the bump every time.
And this is a
FACT that MX Blue will always take more effort to double tap compares to MX Brown and MX Red.

Now does it make enough difference for you to
NOTICE?
I think that depends on people, to me I notice it. Just feels like it takes more effort to spam MX Blue compares to MX Red/Brown. Also MX Blue's high reset point bugs me.
Personally I like MX Red the best for double tap but MX Brown is not bad because it gives you a tiny bump just enough to tell you when the switch is reset.
I mean technically you can double tap with any buttons, even this:

But the question is which would you rather use?
C cup boobs and D cup boobs are both big, but you can't deny the fact that D cup is bigger. But does it warrant enough difference for you to notice?
To me it does
