Haha, nice one! Thanks for that. I made a boo-boo and gave you bad info though sorry, I think it's actually 30 seconds from every 2 mins 30.
Angle 1: St John's (30 secs)
Angle 2: Brentgrovel towards the Grapes (30 secs, 1 min tot)
Angle 3: Ground beneath Greenwoods camera (shot #7 in CCTV identification footage) (30 secs, 1 min 30 tot)
Angle 4: Gregg's Alley (I call it that because you can't see the Horseshoe in this angle) (30 secs, 2 min tot)
Angle 5: Horseshoe (30 secs, 2 min 30 tot)
Angle 3 is not fully validated, but we can deduce from the way the footage is cut (one clip shows Angle 1 to 2, another clip shows angle 4 to 5, and at end of footage we see angle 3 and there's only the Greenwoods camera in that location to see that angle).
Additional footage could come from the Grapes camera (Corrie eating kebab CCTV) but we know nothing about that one as far as I'm aware, because it may also be on an auto-rotation, so unclear how many angles/time has lapsed between each. It wouldn't get great images though, being so far away.
And personally still maintain it may never have started in the Horseshoe at all (ie a car, so never entered any shot ever). What if Corrie looked into the Horseshoe but the car was actually parked in that OTHER horseshoe that's literally round the corner in Short Brackland (another rear of shops, with lots of cars parked in it on Street View, not far from the 'open door' of the back of a pub/kitchen). If that "other" horseshoe was fairly empty at night, perfect place for a car to do a 3 point turn, park up, etc. From the moments we see Corrie walk to the bins, assuming the CCTV moves to Angle 1 seconds later, he then has 2 mins to walk 10 metres out of shot in the Short Brack direction to not be seen on CCTV again.
