Test match cricket, is made 'watchable' by some, for the betting interest, derived by the amount of time that can be lost, due to weather factors.
Normally, a Test consists of 90 overs per day, - so, 5 days, makes 450 overs.
Most games, these days, tend to see results in under 400 overs, (just why that is, is debatable), but, its a happy trend, if you like to watch the weather, and are happy, most days will be interruption free.
(Some days, u get a Get-Out-Of-Jail free card, as time can be made up, with early starts/late finishes, but, this naturally, depends on the weather).
Last yr, there were 57 Tests, with, from memory - 11 draws, of which, only 3, were non rain affected.
So, habitual draw layers, who, laid, with gay abandon, as low as an average 2/1 each game, were certainly, in the money.
This year, all was going swimmingly, with the 1st 10 games, all getting results (not a draw).
Then, the shit has hit the collective fan, with drawn games, in the last few weeks :
Eng v India .. Nagpur ... 17/12/2012
Eng v N.Zealand .. Dunedin .. 10/3/2013
Sri Lanka v Bangladesh .. Galle .. 12/3/2013
and 2 games, looking Drawish on the way, at
Eng v N.Zealand .. Wellington .. 17/3/2013
India v Australia .. Mohali .. 18/3/2013
The volatilty in these games, can be mind-boggling .. u need a v strong stomach, and weather info.
Case in point .. the 4th Day, at Wellington.
Draw crashed to 1.4 pre-play, they actually get some play, and Draw goes odds against.
Meanders around a bit, then Eng get a wkt, and Mr Draw goes 2.3 or so.
Flat pitch (as tweeted, many times, and mizzle/rain comes).
2 hrs later, Mr Draw 1.28, which is a great price ...
