I haven’t seen anyone else call it “effort-based”, but at least one 4-2-5 philosophy is based on quick reads, quick commitments, and speed. If you have a choice between two reads, the best option is to make the right read and get there at 100% speed. The next best option is to make the wrong read, but get there at 100% speed. It’s not GOOD to make the wrong read, but not committing quickly leaves you in no-man’s-land where you can’t get anything done.
