Idea: In-between heart pulses shutter release accessory?

[MichailK]

That is a theoretical question to experienced long lenses shoother (as well as BIF?):

AFAIK, the best moment to release the shutter is about the same as firing a high accuracy firearm - in between the heart pulses that cause a miniscule jitter throughout the body.

Now, we have “smart watches” monitoring heart pulses in real-time.
The newer bodies also have real time bluetooth connection abilities to accesories, right?

Would an accesory/app/whatever that releases the shutter between your heart pulses after you pressed the shutter button provide improvement to long lenses handheld shooting?

What do you think?

(for older bodies this function could be provided with an add-on grip with a separate shutter button along connection to a smartwatch or a dedicated heart monitor bracelet)

It's an interesting idea. At the same time, I think there's a lot of technique involved in getting a steady short before you get to the point where your heartbeat is going to make that much of a difference. So you've got a really small audience for it; people shooting ultra-telephoto who have exhausted the gains from technique. I'm not sure how many people "need" it.

Agreed. If you get to the point where this is the last thing that is making a difference in your hand held shots, then there is this technology called "tripod" one might want to look into.

It's discussed among LR shooters.
In LR F class for distances up to 1000y target's X ring is about 0.5MOA, 10 ring is about 1MOA. Scope magnifications in use are usually 32x plus (more like 42x to 50x), so any movement is seen more clearly.
1MOA means 1" at 100y and 0.5" at 50y, and that's the size of the target to start to worry about when aiming.
But if you really can see "jumping" of the image related to your heartbeat, then maybe it's worth to work on it.
