Chain length 114 links.
Outer links 114/2 = 57 links
Joining link approx £4?
£4 x 57= £228
That's an expensive chain

Far better to clean off the bike - but agree, not with pinned chains, hence quicklink chains.

It depends. On really old-school chains, it's fine. On virtually all modern chsins, it's not. You can get away with it but one day the chain may break 50 miles from home when you don't have a chain tool.

I never even knew this was a thing - must have done this to dozens of chains and never had a problem.

Newer 8,9,10,11,12, use a quick link. I used to re-join chains easily, but not now, the pins/link don't like it.
They are 'peened' as has been mentioned. Quick links are far more convenient and also a good marker to use when oiling a chain.

Most 1/8" chains now seem to be peened too, e.g. SRAM PC-1. With good chainline on the type of bikes they're intended for, it is highly unlikely that a pin will wiggle out, so I'm not sure why they bother.

EEEE (sucks on pipe, offers the listener a Werthers original)
I remember my first quick link. Probably about 1978/9. I mail ordered it and it had two little screws that held the outer plate on. And since then I have only driven links out of chains in order to break them permanently (ie when replacing). Prior to that I always replaced pins and I very frequently made a balls of it.

Whilst it can be done I would recommend using a new pin as my one and only chain failure was after pooh poohing this advice and re-using the old pin. I didn't carry a chain tool then so it was a bit of a bind. This was on a 9 speed probably Shimano chain. That said I've re-used many pins on old 3 speed chains without a problem
About that peened, I wonder what happens when a pin is pushed through a link plate, does the peened end reduce in diameter, or does the plate hole diameter increase, or both?
On my last assemble of two chains (I have to add links from a second to get in on length), after pushing back the pin I gave a hammer blow along a punch on the returned pin end. Just as a try, no idea about the effect it had.

Read my post on the issue. It's illustrated with photos too.
Couldn't find the post with photos.
I did find this though, which may have described it (if same subject) clear enough without need of pics:
"Reusable pins are the ones with two horizontal lines of peening and the non-reusable ones have a peen right round and the pin looks like a circle in a circle".
The pins do have 2 visible lines, not sure what processing methods cause the difference, maybe a punch on the whole surface of the pins (although wouldn't that risk a bend?) end versus 2 simultaneous punches 180 degrees opposed to eachother and under a 45 degrees or so angle so a partly deflection allowing more force without bend risk?
In case, then re-pushing a pin back poses no problem, also didn't experience one.
