Points per player = batting points + bowling points + fielding points
Batting Points
Before batting points are awarded, two 'multipliers' need to be calculated, the runs ratio and the strike rate ration.
Runs scored ratio
To account for the different conditions the batsmen face, the effective total runs scored in the game must be considered for this calulation the total runs scored with availible resources is considered. This is used to scale the effect of runs scored by generating a "runs ratio".
If the second innings is incomplete (the first always will be), an estimate of the final score they would have achieved must be made, to do this the lower total of that assuming overs were the limiting factor or that assuming wickets were the limiting factor is taken:
Total if overs were the limiting factor = Score * (300/balls used)
Total if wickets were the limiting factor = Score * R (R defined from table below)
Code: Select all
Wickets lost: 0 1 2 3 4 5 6 7 8 9 10
Ratio: 100 6.92 3.46 2.34 1.78 1.46 1.28 1.16 1.08 1.03 1
For the purposes of our calculations, we assume the average total runs scored in a match is 410.
example wrote:
Team batting first gets 125ao (45overs).
The chasing team reaches the target to get 127/3 off 34 overs.
Total if overs limiting = 127 * (300/204) = 187
Total if wickets limiting = 127 * 2.34 = 297
So the second innings will be considered to score 187. Therefore the effective total score of the game is 187+125 = 312.
That makes the runs ratio 410/312 = 1.31.
In this game each run scored will earn 1.31 points.
For example, a batsman scoring 45 in the game will earn 45 * 1.31 = 59 points.
Strike rate ratio
The strike rate ratio is calculated using the actual totals and balls faced, simply 100*runs/balls.
For the purposes of our calculations, we assume that 75 runs per 100 balls is the average strikerate for batsmen.
The strike rate ratio = 75/actual strike rate for the match.
This ratio will be used to scale strike rates before assigning strike rate points.

In our example game:
Strike rate ratio = 100*(125+127)/(270+204) = 53
strike rate ratio = 75/53 = 1.42
In this game, each batsman's actual strike rate will be multiplied by 1.42 before awarding strike rate points.
Strike rate bonus/penalty table
Strike rate bonuses are multiplative to the runs scored and calculated from adjusted strike rates.
Adjusted strike rates are calculated by the players strike rate * strike rate ratio.
For example, if a batsman scored 45 from 67 balls, he would have an adjusted strike rate of ( (45/67) * 1.42) = 95.4.
The percentage bonuses/penalties applied are as follows:
Code: Select all
Adjusted strike rate <10 10-34.99 35-59.99 60-84.99 85-109.99 110-159.99 >159.99
% bonus -40% -20% -10% 0 +10% +20% +40%
Milestone points
For scores >=100, 40 bonus points
For scores 50-99, 20 bonus points
For scores 25-49, 10 bonus points
Dismissed, -10 points
Dismissed for a duck, -10 points (so a duck scores -20)
For each six hit, 4 points.
example wrote:
Graham Gordon scores 17 (off 47) in the our example match, with 1 six.
run points = 17 * 1.31 = 22.3 points
dismissed = -10 points
adjusted strikerate = 1.42 * (100*17/47) = 51
strikerate penalty = -10% for strike rate = -2.2 points
sixes = 1 * 4 = 4 points
TOTAL BATTING POINTS = 22.3 -10 -2.2 +4 = 14.1 points
Bowling Points
Points for each wicket
Each wicket scores points based on the batting order position of then batsman dissmissed with this table:
Code: Select all
Batting position: 1 2 3 4 5 6 7 8 9 10 11
Points scored: 26 26 25 24 22 18 14 11 8 6 3
Milestone points
Bonus points are allocated for the number of wickets taken as follows:
2 wickets = 5 points
3 wickets = 10 points
4 wickets = 20 points
5+ wickets = 40 points
Economy points
Points are awarded for economy rate as follows assuming at least 3 complete overs are bowled by the bowler.
Code: Select all
Econ rate: <1.5rpo | 1.5 - 2.49 | 2.5 - 3.49 | 3.5 - 5.49 | 5.5 - 6.49 | 6.5 - 7.49 | > 7.49
Points: 40 20 10 0 -10 -20 -40
Finally, there is a 6 point bonus for each maiden over.
These are added together to gain the total bowling score.
example wrote:
Graham Gordon achieves bowling figures of 3/37 from 10 overs, bowling 1 maiden (his wickets are the 2nd, 3rd and 7th batsmen).
Wicket points = 26+25+14 = 65
Milestone points = 10
Econ points = 0
Maiden pts = 1*6 = 6
TOTAL BOWLING POINTS = 65+10+0+6 = 81.
Fielding Points
Catch by keeper or fielder: 10 points
Stumping by keeper: 10 points
Runout by keeper or fielder: 10 points
example wrote:
Graham Gordon took 2 catches. His fielding points are 2*10=20 points.
Graham Gordon's total points allocated for this match = 14.1 (batting) + 81 (bowling) + 20 (fielding) = 115.1.
