Like others, I can see an improvement. You'll notice this more in the faint areas. The bright stuff gets to a high SNR with a small number of subs and then doesn't improve much more as you add data.

You don't need to filter out the low SNRWeight subs unless they are visibly cloud affected or otherwise damaged. By default, ImageIntegration will do noise weighting and give low weights to these subs but you'll still get some benefit from them.
Are you optimising the rejection settings when you integrate or just using the defaults? That might be a fairly simple way to get some more out of your data.

That's Gerald Wechselberger, aka "oldwexi". He has some good video tutorials on PixelMath and other topics:
