I've read that professional constructors don't use autofill. I'll explain my question.
The autofill often says it can't fill the grid after designing a grid (American style) and putting in the theme words. If I understand this correctly, the autofill would need you to either adjust the grid design, change the order of the theme words, or change some theme words completely.
My question is as follows: If the autofill, which uses word lists that consist of hundreds of thousands of words, can't fill the grid, what are the chances that you would be able to fill it manually?
In other words, wouldn't it make sense to run the autofill a few times only to make sure that technically, there are at least a few possible ways to fill it at all before attempting to fill it manually?
