I haven't personally tested mine in terms of power but pumped 8-10x the internet generally reckons in the 18-22 fpe area.

As for accuracy, my recently refurbished one put pellets into a 10mm group at 20m.  In the past I've shot 1/2" groups at 30m.  So pretty accurate.

Accuracy doesn't seem to be affected by pumps, more like the pellet you choose.  I am confident I could stack pellets at 10m with 4 pumps with the right ammo....

My first airgun was Crosman 760 with rifled barrel.

Easy to shoot accurately compared to springers since there's very little moving mass. Less hold sensitive.

Then I modified a Crosman 2289 pistol (.22) up to around 19 ft-lbs with short barrel.

Made it into a 23 ft-lb rifle with a stock and long barrel. Shot out to 100m.

Around 30 easy strokes for full power.

Then turned my Crosman 760 into a 50 ft-lb pistol.

Also a ground-up 100 ft-lb rifle with free floating barrel so the pressure doesn't alter the accuracy.

The pumper platform is really under-appreciated by manufacturers.

I don't see anything with the quality of high-end springers or PCP's

so it seems a really good pumper needs to be built up.

Using 18.52 grn H&N

Pumps            ft/lb

4                      9.38

5                     11.32

8                     15.6

9                     16.9

10                   18.01

12                   19.5

16                   21.3

So as BC Clark says, there is really a lot more that could be done to develop pumpers, but at 4 pumps, that's a respectable bit of power I reckon.  I see they have put out a pcp version of the 362 called 3622 I think.
