Every statistical algorithm has its limitations and this one is no exception.
However, it's important to outline the limitations that are inherent in this objective ranking system.
1. The formula can't account for the match situation. Therefore, runs and wickets compiled in pressured situations don't carry more significance than those accumulated at other times.
2. The system can only judge a player on the accumulated statistics identified in the points-allocation slide. For example, a bowler who goes wicketless in an impressive spell will receive fewer points than a bowler who claims two fortunate wickets in an otherwise loose spell.
3. In using par-adjusted strikes rates, the algorithm cannot determine if a player was forced to operate in a defensive manner following the loss of wickets.
4. The system can't account for the varying degrees of scoring that occur in different conditions and venues.
5. By judging players on a per-innings basis, this system will inherently favour those who have competed in fewer innings, as it's easier to maintain higher levels of performance across shorter time periods.
6. Another downfall of evaluating players on a per-innings basis is that all-rounders are hurt by their performances in a match representing two separate scores rather than one.
