Hi Matthew, It is more likely you will wish to have A3 to A4 slightly larger than a 4:2. It would be better to use F3 to A3 then F3 to A4 and listen to the resulting beat at A5. Ghosting by holding down A3 and A4 (silently) then playing A5 FF staccato would give you a "zero beat" result for a perfect 4:2. Better to ghost F3 A3 (with A5) then ghost F3 A4 (with A5). That way you will have an audible beat (rather than zero beating) and will know which way to move A3 depending on the beat speed. If F3 A3 is faster than F3 A4 then A3 to A4 is larger than 4:2. If F3 A3 is slower than F3 A4 then A3 to A4 is smaller than 4:2. I hope this helps! Good luck.
