I'm surprised you really need to start this up again, this was all covered only a few pages ago.
At the time I started the manoeuvre the "overtakee" was not driving unpredictably, just slow, so I opted to overtake him. It was not until I was pretty much already past him (overtaking casually, not gunning it) that he decided to boot it.
There is no way to foresee someone deciding to do this, you just can't expect anyone to see this happening, otherwise you're suggesting that no one should overtake, ever.
The only possible argument was how I decided to handle the situation. With cars behind me and him, and my acceleration advantage, I decided to go past rather than to hang back.
It was a split second decision, but one that in hindsight I do not regret - better a speeding ticket than potentially being rear-ended.
