Thanks for this novel word “comaparison”.
I would normally have some doubts as it is unfamiliar to me and I can also not find it any dictionary, but since you have been teaching English for a long time, I regard your contribution as valid and correct.
I did spend a few days in coma myself not too many moons ago but I can’t recall that fact very much and I am unaware of how other comas normally progress so I could not help in providing any comaparison.
(Don’t you just hate foreigners, especially if they come from abroad?)
Goes to show; one can never be too Dutch to learn some crookeder English.
