I like grouping hazards, probably mentioned it, because sometimes you can make a single set of actions do both or all, less effort! However sometimes it's counter-productive and leads to a less nice outcome.

I may have heard it from the MSF, one the areas covered under positioning (bikes, as a benefit of narrow width relative to the lane). One example is approaching a junction on the left where there are two other vehicles waiting, one to turn out the other turn across.

One option is to choose a central line, mid-way between the two hazards. An alternative is to manage the situation by allowing one vehicle to turn so that you can then position further away from the remaining vehicle. Separation by time or distance.

Another would be a blind junction on the outside of a tight right bend. In addition to the bend, there's real possibility of vehicles emerging (even if only trying to get a view) or an oncoming vehicle wanting to turn across.
Your 'standard' is how you drive alone, not how you drive during a test.

Some block-up before reaching their desired speed, which just takes more time and reduces progress. Makes me wonder if they are just following the pattern rather than understanding why and when; if they are not getting on with it, does holding a lower gear for longer confer any advantage?

Reduces progress?
I frequently come off a roundabout in third at 30-ish and accelerate to 70 then change into 6th. I am certainly going beyond peak power, but the time taken to change through two intermediate gears is saved and it pulls to NSL well enough to pull away from most of the people who have been trying to sit on my tail and push past in the roundabout (who appear to be taking time to change one gear at a time, as they drop back in two stages).
It's probably important on vehicles with a narrower, steeper power curve. On a standard modern car like a Nissan Pulsar it certainly seems quicker to just hold the lower gear.

The sort of sequence I meant was accelerate in third up until, say, 55 then block change up a couple of gears then continuing to accelerate to 70. So, starting off with quite a bit of acceleration, changing up, then less acceleration.
