Think factory default settings are
op 200
semi-auto,
dwell 28 flashes (7ms),
rof 13 bps (bit of a guess that, I had to set mine at 10 for site-compliance),
bip 1ms.
Try op 180
semi-auto
dwell 24
back-cap 3 complete turns out from fully in. Have a go with those over a chrono & let us know the results.
