A bit under 19 times 5 days

So, 93 or 94 days.

About May 6th.

The minute you hear the phrase: 'Exponential increase.'

Run like F***. (Not 'away,' but toward the pub. You might make it that far …. ) :buddy:

Unless the phrase is used by a politician … in which case … take all the time you need to get to the pub … bearing in mind said politician will probably have jacked up the prices by the time you get there.

:bum:
