Centaurus, great post and will try your technique next time in the sim but like to start the inital turn at 700 feet to keep the circuit a bit tighter.
Another tip is to keep an eye on the airfield by setting it up on map mode with an extended centerline.
Not sure which of these you are after but here goes:
1.Circling Approach-
Config at MDA(H): Gear down,flap15,speedbrake armed, verify alt hold, set missed approach alt, HDG SELECT offset 45degrees track, timing 20 secs from wings level.
Abeam threshold:Timing-3 seconds per 100ft AGL. Wind correction 1/2 TWC or HWC(kts) in seconds.
Turning base leg: Set Rwy heading, landing flaps, call for landing checklist.
Intercept the normal visual glide path and disconnect A/P and A/T, recycle FD's
Follow the PAPIs in.
2.Visual Traffic Pattern-
10nm from touchdown set flaps 1
Entering downwind set flaps 5
Abeam threshold set missed approach altitude and recycle FD's
Before base turn, Gear down, flap15, landing checklist to flaps
Turning base, Flaps25 and start descent if needed
Base, landing flaps and complete lading checklist
500ft be stabilized on profile.
3.Circuit training-
Upwind, Gear up, 400agl with white bug increasing Flap5 and turn downwind
Downwind, complete after take off checks and descent and approach checks
Abeam threshold, timing(T) 30secs +/- 1/2 total wind correction
Before turning base, T+30, gear down, flap15, landing checklist to flaps
T+45, flaps25, turn base, descend at 500fpm
Approaching profile, landing flaps, landing checklist but do not arm speedbrake or autobrakes for touch and go
Main wheel touchdown, Advance throust levers to approx 60-70% N1
After nosewheel touchdown, flap15, trim to approx 5.5units
PNF call "Go", advance to approx 90% N1, call "Set takeoff thrust"
And around you go again!!
