Olinpump 15-45: is this an issue or not?

Hello, I just bought a used Olin 15-45 and I am wondering if I have an issue, or if this is normal.

The s-tube cylinder seems to kick when it retracts, but I am unsure if it is normal to move that fast compared to the extension (I have read that retract is usually faster.).

I took a video of it:

Is this a normal cycle for a single cylinder s-tube assembly? Or should I look into getting it addressed?

Any and all help is greatly appreciated

Now, after watching more videos, I am wondering if the extension part is too slow (instead of the retraction being fast)

Does it look slow or lagging to anyone else?

the badder of your surge chamber is old. they are $ 300- bucks plus the $30- nitrogen recharge and what ever labor. when its shifting on the slow side its running off the main pump. gets a little pressure on the other stroke.
