If {pa roi ko'a} means, roughly, {pa roi ca ko'a} xor {ca ko'a
pa roi}, doesn't that imply that the tag's relation to its own
sumti is at the same level as its relation to its sister sumti?

(What's the difference between 'rotate' and 'revolve'? I'm sure
John will enjoy telling me...)

I thought it was 'minute', but that seemed less plausible & I was
too lazy to look it up.

It is three separate lengths, but they can perfectly well be
contiguous -- cf "I travelled just the once, on Monday, Tuesday,
and Wednesday".

So {re roi ci djedi cu klama} would mean "travel twice, each
travelling occuring on each of three things of a day's duration".

Okay, but I don't see the problem there with that meaning.

That's not how I'd read {ca ci djedi} -- I'd say it says something
happens on day 1, day 2 and day 3, but not that it necessarily
happens three times. E.g. {mi zvati la paris ca re djedi} is 
sensical if I went there for a weekend trip.

Okay, but I need more persuading on this.

Fair enough, but the default left-to-right scope rule *is* the 
standard rule, and unless there are good reasons to the contrary,
we assume that it applies even to cases that haven't been discussed.
