How far can you push IS in the real world?

The photo below was taken completely handheld on a full frame body at 70mm. Using traditional wisdom, I would've needed to shoot at 1/70th of a second to avoid camera shake. I managed to get this level of stability at 1/5th of a second, which is not far off 4 full stops of stabilisation if I've done my maths correctly? This is with the in-body stabilisation on a Canon R6 and the lens stabilisation on a Tamron 24-70mm. I can't wait to see what sort of results I'll be able to get from an Canon RF lens where the lens and body IS are optimised to work together!

What sort of experience do others find in the real world?

I was experimenting with some day-time long exposures using a neutral density filter and took this shot in central Manchester, aiming to get some motion blur from the pedestrians, with the buildings and hard landscaping sharp enough to generate some contrast.

This one was handheld at 1 sec using an R5 and RF 24-105 f4 L lens (at 24mm and f4.5, ISO3200). So about 5 stops of IS.

it's not as sharp as it would have been if I'd used a tripod, but handheld at 1 sec would have been unthinkable without the IS.

You have to bear in mind the focal length. The wider it is the more you can get away with. So your task at 24mm was 'easier' than the OPs at 70mm. Good result though.

Both of these are handheld as I’m too lazy to carry a tripod

I shoot a D750, D500, and a Z6. I have IS on my 70-200 f2.8 and my 200-500 f5.6. Real world answer is one stop and even then I would rather crank up the ISO unless the light is really poor.

3200 on the 750, 6400 on the other two. Only then do I flick that switch.
