The Trend Setter (TS)

TS is the player which does the best in a criteria. The rating of all other players are calculated taking the TS as the benchmark. Know All About TS. Here is an example:-

TS 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)

Some sections consider performances only against the top teams. Here is some information about the Top Teams:-

Win/Loss Ratio is used to determine top teams.
The top teams are calculated by decades.
Further, they are divided into In Asia and Outside Asia.
A bowler's performace is counted in TT if it comes in the specific condition and in the specific decade.
