Have quickly crunched the DRS stats to date-
Holdstock (2 Tests)- 3 overturned from 8 (37.5%)
Menon (2 Tests)- 6 overturned from 14 (42.9%)
Sharfuddoula (1)- 2 overturned from 6 (33.3%)
Raza (1)- 0 overturned from 6 (albeit aided by the Weatherald non-review)
So objectively for 3 of 4 an above average rate both for them personally and for the Elite Panel more broadly
Final numbers:
Holdstock (2 Tests)- 3 overturned from 8 (37.5%)
Menon (2 Tests)- 6 overturned from 14 (42.9%)
Sharfuddoula (1)- 2 overturned from 6 (33.3%)
Raza (2)- 0 overturned from 15 (again with some luck)
Dharmasena (1)- 0 overturned from 7
Gaffaney (2)- 4 overturned from 9 (44.4%)
Obviously Raza got the Weatherald LBW wrong, but those are very impressive stats. His only other blemishes were calling leg byes before review in Sydney, and potentially the controversial Weatherald caught behind which was not overturned.
He had a shocker in the series prior in Bangladesh but has bounced back really well in an important series.
