  • I should think both are acceptable, but I would prefer the first sentence (90%+). One could say, "I have a success rate of greater than (or more than) 90% according to all measures". – tautophile Jun 18 '18 at 20:15

    This doesn't have much to do with the English language, though. It's a question about arranging a collection of mathematical symbols, not the nuts and bolts of the English language. – Andrew Leach Jun 18 '18 at 20:16
  • I tend to write %+ and read it as "percent or more". This is a personal preference, though. – psosuna Jun 18 '18 at 20:16
  • how about >90%? – Azor Ahai Jun 18 '18 at 20:40

Since it seems that symbols can be used (otherwise, we wouldn't see a %+ or +%, and the question is asking to convert the words to symbols:

I have a ≥ 90% success rate across the board.

If the choice really is only between the two sample sentences, exactly as written, it seems to me that it's purely a matter of style. (If forced, I would pick the first sentence. But I wouldn't be following any rule for it.)
