Sadly NASCAR seem to have come up with another 'Bums on Seats' set of regulations with the 'Chase' rubbish.
Every championship I know of is decided over a full season, not the best of five or ten or twenty, and if the title is decided before the end of the season then that's the way it goes.
Look at EffWun this year, 'Little Sebastian' NEVER lead the Drivers Championship until the end of the final round, and that is the one that counts.
FWIW, I hear his home town has re-named itself after Sebbie, odd name for a town 'Bastardstein' but them Chermans are a weird lot!!
Back to NASCAR,
" With some luck (and Martin not deliberately blowing an engine) Jimmie could easy be a 7 time in a row champion." ............. you're good for a giggle Ed!!

Let's face it, NASCAR is a domestic series peculiar to the US, mainly for the purpose of making as much money as possible and by any method, who could care less for the audience except for their wallets!!
We appear to be cursed with an 'entrepreneur' who seems to regard himself as a cross between Ecclestone and France (or whoever runs NASCAR today!) and is following the same route, spec chassis, spec rubber, enforced pit stops (needed or not!) and the liberal use of safety cars and yellow flags just in case a talented driver gets away.
The ONLY differences between our V8 Supercars are the power plant (both US models BTW) and the silhouette body shell.
'Fords' use GMH suspension parts and 'Commodores' run Ford rear ends, both 'Manufacturers' run the same wheels, brakes and sundry items...... if 'Cockhead' goes much further the cars will be like the NASCAR 'variations' with stick-on lights and different engines but not much else.
Like so many 'Sporting' series today both NASCAR and our Aussie V8 series are being dumbed down to appeal to the bottom of the food chain.
My 2c worth!
PS: our $ is worth more than yours at the moment so that would be worth 3c in our money1
