I've broken my brain to keep my drabbles 100 words, because telling that short a story and making it complete is hard work - and very much worth the effort if it's done right. That's the point of having such a very short form - to meet that challenge.
A 950 story is a short-short. Or a vignette. Calling it a drabble would be like writing sonnet and calling it a limerick. Both have their points, but they aren't the same.
