I am about to do an endorsement on the Robbo...so am quite interested in this topic.
Surely the flare-or-not-to-flare question depends on your heigh/velocity predicament? I was always taught to just lower the bloody lever, keep it in balance and go for the correct speed - depending on your aimpoint. Automatically entering a flare could be risky, lest you be left at the wrong height with no speed?
