Answers.Text: Yeah, 0.0 is about 1000 moves behind the horizon :-) (I still got a position which is +99 on LiChess, so you are not even close :P)

Body: <p>Since the question in this form is somewhat ill-defined,
  I elaborate on it so it can be solved by experiment:</p>
  <p>What is the maximum centipawn value you can come up with so that the weaker side holds a draw?</p>
  <p>Assume two very strong deterministic (i.e., you only need one game) computers play out a position which is very bad (with value c centipawns) for one side, but the weaker side still draws. Say, two Leela copies. (Fortresses would be the first thing I'd try. But they neither may be solvable by tablebases nor a draw by 50 move/3 repetitions inside the horizon, otherwise it's an immediate 0.0!)</p>
  <p>P.S. For a &quot;normal&quot; position I expect a guaranteed win somewhere in the evaluation range +2 to +3.</p>

  This position looks familiar, doesn't it? ;)
  As you can check on lichess, the evaluation is nearly +8, and yet the position is as dead as it can be...
  [Title "Diagram from Black's perspective"]
  [FEN "kR6/p1p1p1p1/P1P1P1P1/p1p1p1p1/8/8/PKP1P1P1/8 b - - 0 1"] 
  [startlfipped ""]
  
  There are countless such examples, check this and this.
  If you want to know the practical winning centipawn threshold (arising in realistic games), my guess would be something near 1.5.
