Thanks for the work on the proposed summary.

Looks good to me.

I think it would be easier to demonstrate the interference with a single example, rather than requiring a formal demonstration that their can't be interference.

IOW, if one believes that there is interference, please explicit the case.

Could this be rephrased along this line?

Thanks,
