Just now, Back Brewing said:

Great info I've seen and read where you can only do it on the same yeast slurry using the jar method 4 or 5 times but you got 2.5 years gives me confidence to do it experiment more

It might be strain dependent, though I don't actually know for sure.  Kveik yeasts are generally pretty robust and resilient strains so that might contribute to their ability to be reused countless times without any apparent deterioration.

Thanks @BlackSands Sandman! Looks like mine will be fine then - stored indoors at 20 degrees C. 
Some of the ones I stored at 30 degrees for a week or so were fine - though a little undercarbonated. I suspect though that is due to only using 2 carb drops instead of my usual heaped sugar measure
