How much longer have I got on this chainring?

Was doing some maintenance and noted the chainring looked pretty sharp.

How much longer before this goes to the scrappy?

I put it on in May 2020

Cassette is a warranty replacement I put on in august 21 due to big cassette ring shedding multiple teeth

Chain is a XX1 I put on with the cassette.
at the same time I also upgraded to gxs derailleur

I think its done ~ 4+k miles, Its all had a hard life

most of it on stony sandy loamy gritty fire roads with loamy trails.

do I need to replace the cassette, chain & chainring or would I get away with just a new chain ring?

xx1 chain has been amazingly reliable considering how bad I treat it.

I might wait till the cassette goes before replacing the lot but not sure teh chainring will make it.

If the bike is lucky it'll get a quick rinse when I come back, the last few months I either get back in the dark or need to jump on a work meeting so it gets thrown in the bike garage (aka shed) without a wash and the chain gets a lube just before heading out the next ride.

how worn can it get

cassete not too bad

missing teeth that was warranty replaced in 21

what a chainring should look like
