I've read in [Wikipedia](https://en.wikipedia.org/wiki/Mesomeric_effect#:~:text=The%20mesomeric%20effect%20in%20chemistry,present%20on%20an%20adjacent%20atom) about +M strength of groups which goes:
> –O __-__ > –NH2 > __–NHCOR > –OR__ > –OCOR > –Ph > –CH3 > –F > –Cl > –Br > –I

Now in every other website states that in terms of +M strength:

# My question: #
Can you please verify the series and explain the reason if -OR actually has less activity than -NHCOR?

* Also since in -NH of -NHCOR there is an EWG(Electron withdrawing group) which is -COCH3 which should decrease the +M strength of the group appreciably.
