It's expressible thus: 172IRB =80MPV if 1=?
Or, as that true man of Somerset Vic Marks put it in the Observer today, 'In the currency of the day, an 80 from Vaughan against Durham is probably the equivalent of Bell's 172 at Taunton, where April runs are as much a part of spring as primroses in the hedgerows'.
While Vaughan's '80' against Durham remains purely theoretical, Bell's 172 must be contextualised by James Hildreth's 303*, Craig Kieswetter's 150*, Wawickshire's 500 and 108-1 and Somerset's 672-4 - and by the fact that it is against the physical laws of the universe not to score runs at Taunton.
So how much is one run worth there? Over to you, stattos. It's all too much for the England selectors, who need another week to mull over the first squad of the year.
That Taunton Paradox. It'll get you every time.
