With just 19 qualifying rounds to go it would be fair to say a 134 or better will keep you in the final. There is 10 players sitting on 136 and another 12 players 2 or less strokes behind.  Remember at this stage you need to better a current score to qualify, in other words a 136 will not get you into a qualifying position, you will need a 135 or better. Please see [here] for the current leader board as it stands as at 14 February 21.
