Greg,
I may well be wrong, but I don’t see it.
If it’s ‘tested’: to me there are four letters after the ‘T’, and I can’t stretch ‘ed’ out to four letter spacing.
While ‘incl’ has four letters and fits in that regard, it lacks the spacing between words (‘test’ and ‘incl’) that to me is prominent between all other words.
But I really like the idea of the first letter being ‘A’ - I’ve run through the alphabet a few times using each letter to see what sparked... never came up with ‘Air’
Thanks for the spark - let me re-think things.
