Feedback on "...as soon as ..."

The sentence is very passive in voice. There's a glut of helping verbs that I'd recommend you avoid, especially since this appears to be somewhat-academic. Other small note, I think you should use proven over proved here. Proved would be used when the proving is a complete event in the past. Proven implies that they may still ongoing.

If you're trying to get someone off your back about a deadline, maybe start off with the prerequisite events: "As soon as the results are proven, we will determine the order of X."

Or if you like your current structure: "Our team will determine the order of X as soon as the the following results are proven."

Last note - the way you have written the determining implies that anyone may be determining the order of X. If you know, just say it. "Me/I" or "we" or "the study team" or whatever it may be gives the reader more context with very little extra writing.

Active, concise writing is always the goal!
