I’m not sure what you mean by over cutting the notch, the pic with the 500i in it?Looks like being frozen may have been all that was keeping some of those together.
I would tentative suggest you need to work on your felling cuts, particularly not overcutting the notch or the back cut. As mentioned above, you're playing with fire with these trees... so best not to give em any more reason for things to "go sideways"

This statement is concerning on several levels... I hope you're not cutting alone out thereThe other two joined trees I was cutting over my head about 6’ high so not too concerned about matching cuts at that point.
