5 test series comfortably yes
I did not know until yesterday Stokes has as many fc hundreds as Root and is younger
First you diss Joe Root, then your forum starts playing up. Coincidence?

How about a bet then if Pujara and Root play all 5 matches?
Either ...
If Root scores most runs in the series, I win.
If Pujara scores 150 runs more than Root in the series, you win.
(if it is inbetween, it is a draw).
Or, on my calculations: 150/5 matches = 30 a match /2 inns = 15 runs per innings.
If Root averages more than Pujara, I win.
If Pujura averages 15 more than Root, you win.
(if it is inbetween, it is a draw).
This way should negate the rain factor.
Loser needs to put a comment, such as "joeljonno was right, Root won" or "procricket was right, Pujara is streets ahead" in your footer for 3 months from the day after the last test?
