BRIEF EXPLANATION

Dynamic Nature

Most of our ratings are dynamic, and as new matches are played, the rating of earlier bowlers may change if current bowlers set new benchmarks.

Trend Setter (TS)

TS is the player who does the best in a criteria.
The rating of all other players are calculated taking the TS as the benchmark. Example:-
TS Bowling Ave: 25.00; Player X Ave: 30.00; Section Points: 300.00
TS Points: 300.00 (Max)
Player X Points: TS Ave/Ave X 300 = 25.00/30.00 X 300 = 250.00.
Ratings of all sections are calculated similarly with Ave being replaced by the Criteria Stat.

Top Teams (TT)

An opposition is counted as a TT considering its Win/Loss (WL) Ratios in last 5 years.
Home, Away, In Asia, Outside Asia and Overall WL Ratio is considered.
The WL Ratio should be more than a certain value overall or in specific conditions.

Top Inns by ER (BBE) Qualification

Overs bowled in the innings must be more than 50% of the allotted overs for a bowler in the match.
This is generally 30 balls for a 50 over match and 36 balls for a 60 over match.
However it may be less if the match is shortened for some reason.
