Virtuoso Analysis

[Nirvanam]

Folks, I need your inputs on what would be the right criteria (parameters) for a comprehensive Virtuoso Analysis of the 16 ATG batsmen. The previous one included the following - 1. Career performance Index - performance over entire career 2. Top Opposition Index - performance versus the best opposition of the player's time 3. Condition Difficulty Index - performance on the hardest of wickets: in 3 categories, Dust Bowls, Swing/Seam Havens, Speed Roads 4. Career Ratings Index - ICC ratings 5. Bowler Challenge Index - top 10 bowlers as per ICC ratings 6. Dependability Index - best and worst 80 innings stretch. For the firs 3 criteria, the metric is Index = 0.5*Avg.Index + 0.25*IpC.Index + 0.15*IpF.Index + 0.1*IpB.Index where IpC = Inns/Cent, IpF = Inns/Fifty, and IpB = Inns/Big Ones (150s). The virtuoso-ness of the batsman can be gaged by - a. how good he was against the best bowlers of his time b. how good he was on the most difficult of pitches c. his consistency d. overall how good he was against all opposition. Please give me your suggestions to improve the above criteria.
