best guess

Likeliest answer offered

A best guess is an estimate made with incomplete information—the most reasonable answer you can offer when certainty isn't possible.

It acknowledges uncertainty while still committing to a position: My best guess is we'll arrive around noon.

The phrase often appears when someone is pressed for an answer they can't fully support: If I had to give you my best guess, I'd say the project will take six months.
