Need more diversity among unpires

Was watch the Aussie 2nd inning vs Sri Lanka today. Steve Smith got a thick edge and was given not out by Gafne. DRS showed out. So out.

Mitchel Marsh given not out by Kettle Boro off Perreira. DR’S showed ball hitting 50 pct of leg stump and height wise just below bails. Enough doubt. So “call on ground stands”.

A little later Mitchell Marsh given not out by Kettle Boro off Lakshman. DR’S showed out.

So two outs and one 50 50, all back to back decisions go the Aussie way. If we assign 1/2 to odds of 50 50, and 1/6 to odds of clear out not given out, my supercomputer shows odds are one out of 72 that all 3 decisions on the ground wouod favor Australia.

But all 3 decisions back to back did favor Australia.

Umpire of the more tanned variety would probably even the scales a bit. It does appear right now all “shouts” from Aussies are good shouts, and from sub continent not so much.
