I need to refer to predictions I made that were not a 100% success, but a 90+% success.
I first wrote "with some success" but a native english speaker (I am not) reviewed it and told me "some success" did not sound very successful.
How I express the results were good enough for me to be completely satisfied by them without being perfect, and not sound to be bragging about it?
When you're talking about personal success some people may perceive you as bragging or immodest regardless of how you present yourself. This is probably more true when referring to a perfect or near perfect performance.
I would suggest an honest and accurate characterization using objective and straightforward language.
Consider these phrases:
...and since we're talking about predictions:
If you are actually objectively correct 90/100 times, then just use the 90% figure.
If you are being subjective, I would say "great success" or "successful more times than not."
You could call it a "high rate of success" or "highly successful". Or, your predictions were made with "good/excellent accuracy". Your colleague is correct, saying "some success" suggests fairly mediocre performance.
