I’ll give you a short answer as you’ve got a lot of detailed ones already: to a native British English speaker “six oh five a m” sounds completely normal. There are other ways to say it that sound equally normal.
+1 for Morrisons. They don’t often sub and when they do it’s usually not completely mad. We found it was significantly better than the others. I think it’s because they use Ocado’s tech rather than whatever bodge the other supermarkets have come up with.
Ocado was also good when we tried it ages ago but of course quite pricey (and the last thing I need is easier access to Percy Pigs).
Not a direct answer to the question but one thing not noted in other answers is in computing you often work at a higher precision than you need for your final answer as the errors tend to increase each time you do a mathematical operation.
In the world of reasonably powerful hardware (laptops, desktops, servers, smart phones etc.) we’d typically work with 64 bit floating point numbers which gives pi to 15 digits (I think, not at a real computer now so can’t check). because it’s simple to do so even though we don’t need the full precision.
I’ve heard it suggested that they didn’t expect to get as far as they did into Israel and they barely expected to get past the border wall. If that’s the case they may not have planned what to do when they did and so there may be no grand strategy behind some or all of it.
I guess we’ll never know.
I’m not a big important decision maker but if I always came across your website when searching for answers about software X and your GitHub when looking for code for software X I would go to my manager and say “why don’t we just pay this person to sort it out, they seem to know their stuff” and there’s a fair chance we’d do it.
