The %% are supposed to tell how deep the balls are buried in grass or sand.
And yes, there are a few numerical hints - saerch! =>
My take is, no woods from light rough, only punches from deeper rough. Aim for the fairway and expect the ball to touch ground again soon.
From bunkers of 30% up, only wedges.
You are L1. Replace at least one wedge with a custom one (from L7 up).
