I started at about 200 jumps under a saber 2 170 wingload at 1.2. I started by creating a consistent diving time under double front. After 30-50 jumps I start doing 90. Before this while doing double front I start building up my set up by doing drills up high and building an average on altitude lost, also doing carvings up high, simulate for when I would need to bail (this have saved my ass a few time and will keep on doing so). I did about 250 jumps in a period of 2 months and at least 200 jumps were high hop and pops. Before I even though on doing any of this I was able to land my canopy where I wanted, I could land on cross wind, downwind, do clean flat turns at any altitude.
After many hop and pops and a developing my skill in a progressive way I got clearance from my canopy coach and almost 400 jumps later I am on a crossfire2 139 WL 1.6
