Lets say at 80mph, what is an instant? 6inches? a foot?

technically....it would be like a nanometer....but effectively you are probably within 95% to 100% of max speed for about a foot of arc length I would guess.
That number is totally out of my rear though. Just based on my own swing and how far the ball goes when I am slightly late or early vs hitting it just right.

good video on impact, hand speed and to not reach max speed late or early.

And how important LAG is to the swing, and extension, and not rolling over early.
Bottom line, increase your speed into impact.
BAD chart, where to improve.
Its interesting that in golf the club head is still accelerating after impact, imagine if you could do that with a bat...... fastpitch fences would be at 300'!! Oh yea, we are suppose to slow down before impact.

Bat Speed At Impact is greatly influenced by contact location. Hitters maximize their bat speed right around the front of their stride foot and at a height of about 40% of their height (roughly where their hand is when their arm at their side). This location gives you the best chance to time your bat speed so that your Max bat speed occurs at impact. the goal
In the chart above max barrel speed occurs just prior to impact.

Interesting chart.
Obviously 'impact' doesn't occur over such a range ... that would look a bit odd having the ball stick to the club head for such a period of time. Impact is of course more of a single point. For example ... the vertical dashed line in the center of the green shaded area, or one of the vertical dashed lines on either edge of the green shaded area.
Perhaps that's why the verbiage of "BAD chart, where to improve"?
Perhaps the point is that 'relative' to peak speed that what is good is the 'center vertical dashed line' and what is bad is the 'vertical dashed lines' on the edges.
Often the goal is to get the maximum club speed occurring close to impact.

If the club head is still accelerating post impact then release mechanics going into and through impact where not ideal ... and club head speed was compromised.
The 'intent' is not to purposely slow the barrel down prior to impact ... it is more of a goal to throw the barrel head through the ball towards extension ... with the result being that maximum barrel speed is realized virtually at impact, albeit slightly ahead of impact. The notion suggested earlier that barrel speed is maximized and maintained is not correct.
Proper release mechanics, along with a downstream mentality of throwing the bat head to extension, can give the 'feel' that velocity peaks post impact, but on a good swing the barrel speed will peak virtually at impact ... and occur slightly ahead of impact.
My guess that the sharp drop is caused by impact, but I would like to see a chart with no impact, just the dry swing.
You say that there is no, none, maintained max speed, and to ideally reach and start losing it before contact.
I agree with JJ on the distance the max speed of about a foot, but that number is also just a guess.
I like how you are saying zepp is wrong, along with all its reps, zepp would like contact to be at max speed.
now here is the kicker, since impact causes this sharp drop, and max bat speed should be at impact, it would be hard to tell if the bat is still accelerating at impact, because of impact.

That is not at all what we are saying, we are saying that while you look at this picture and think that the time that the ball is in this position is long enough for the hands to play a role, that it simply does not due to the physics of the bat ball collision. To give you a reference point at this time, the batter does not even know they made contact yetl. A bat is not a perfectly rigid object that transfers energy instantly from hands to ball, it is a sort of spring and there is a propagation time for the energy to travel from hands to barrel, this time is LONGER than the bat ball collision so it is PHYSICALLY IMPOSSIBLE for the hands to play a role after contact has initiated. Have you even looked at any of the studies that show that exit speed is constant when a bat is bolted to a wall and when it is hanging from a string?
I have not seen those studies, if you could please put up a link here, I will take a look. It be worth seeing exit speed when the bat is dangling from a string, in my mind I see the ball not going as far as the rigid bat.
The hands don't just play a role after contact.... they do before, during, and after contact, to help sustain batspeed
