Nearly all my stories for competitions are right on the word limit. I used to be hopeless and go way over in my early drafts and have to edit hard. But nowadays I'm getting more accurate from the get go; indeed with this story I naturally hit 1000 +/- five words all through the drafting and editing stages. Though I do find Grammarly suggests more hyphens than I instinctively use.
Both Word and Google docs have the same word count I've found. I tend to write in Goggle docs as I'm doing more on my phone nowadays (I'm sure those who know me will know why,) but generally I copy the story into Word and submit from that, as it holds the formatting better than submitting from Google docs.
The word count increased when I submitted my story here, by one word, not sure why. I thought I understood the mechanics as the last time on the other site, the word count went up by the number of words in the one-liner. Not this time.

What a great expression, I'm going to borrow that.
