As above, you need to get the habit of judging RoD from the visual perspective. The trouble with looking in "if I would continue to do this till I... feel experienced enough?" is you will not get the experience
In addition, whilst the Airbus RoD is instantaneous, it might fail / misread, but also it cannot allow for Runway slope, which the visual judgement will.
Not even here until I messed up that landing. I hadn't flared enough and wasn't aware of it. Had me feeling like crap for a while.
I've got 12K+ hours, A320 command since 2003, and still "mess up" some landings. All my experience means is is I don't "feel like crap for a while"
