No, our methodology is nowhere near as complicated as the musings of one of our more recent talked-about coaches.
Even though we cannot provide the exact calculations here because the system is proprietary for obvious reasons, the outline of the structure is provided below. We will make our calculations public once our patent is not pending anymore. Fundamentally, it is possible to do all these calculations outlined below manually too, at the back of an envelope, once the system is understood. It is obviously not possible to do this without knowing the exact values and the structure of interdependent values, but the outline below provides a bird’s-eye-view. To save time and energy, we have automated the entire system and run all cricket data through it.
A simplified step-by-step list of its mechanism is given below, in case you want to understand how it really works. This methodology below is for limited over matches; it is a little more complex for Tests.
1) Based on the innings totals, a base figure is generated for the match. This is measured in runs, for all players (batsmen and bowlers and wicket-keepers).
2) Every performance in the match is thereafter measured against this base figure (as a ratio). An Impact value of 1 is procured when the performance is equal to the base. That is seen as merely the par performance for the match.
3) For a batsman, Impact value constitutes a) Runs Tally b) Strike Rate c) Pressure d) Partnership-Building and e) Chasing and staying not out in the second innings (limited overs) or f)
6) For a bowler, Impact points are garnered for a) Wickets (the top 8 wickets and the last 3 have different values, in most cases, as per the circumstances of the match) b) the Economy Rate (again, calculated against the base economy rate of the match – in T20 matches, the economy rate has a slightly higher value, as per the circumstances of the match) c) Breaking Partnerships (its limit is set by using a multiple of the base) d) Building Pressure (taking quick wickets within the base).
*In Test cricket, the top 7 wickets and the last 4 have different values, as per the circumstances of the match.
7) Catches, stumpings and credited run-outs all get extra Impact value (a fraction of the base). The winning captain also gets an addition to his Impact (again, a fraction of the base). Wicket-keepers have a flat value for doing an assigned job (which is gleaned from Test, ODI or T20 history).
8) All the above points are measured against the base figure, and are therefore ratios of the base in some way (which is fundamentally why they are measurements and not ratings).
9) For Strength of Opposition – all teams in all matches are graded in categories of A, B or C in terms of team strength (with A being the strongest). The break-up is done in a scientific manner, using the previous 3 series as a pointer, and also the result of that series.
10) For Series/Tournament Defining performances (
11) In a career context, the figures from all heads are tallied. All numbers are restricted between 0 and 5, up to two decimal points. However, in a match context, the numbers are not restricted.
For simplicity, we change the scale in our match reports (commencing with IPL 2016) and express every
