could you please proofread the following sentence:
So-called ABC models still used in case of a high number of structures practically do not work in fact. (meaning that they almost do not work in fact).
The end of the sentence doesn´t seem correct ...
Thank you very much.
Thank you! But this means that they do not work at all and I am trying to say that they almost do not work or hardly work in practicee.
How about: "do not always work in practice" OR "do not necessarily work in practice"?
