I warned you at the start: There are many questions. I have moved on, but in a spiral fashion The question will be re-visited but for now Ive got enough working possibilities to get on with.

The pattern itself looks like:
Of course Ill have a think on it. But the (temporary) conclusion Ive come to is as I stated earlier: a distributed statistical sample (I dont have the language, but I know what I mean ) seems to be the most efficient approach. For now Ill settle for the brute force "methodology", as I reckon that itll be a one-off cost in most instances, applied to mainly older, unchanging files. A user making new screen dumps would then hopefully learn to use _scr4 and _scr8 extension names in the future..
