I guess this is just another case of stats, damned stats & different outcomes.

I think its correct to state that Chrome's database only records metro meetings, not sure if only the Saturday metro races are recorded or all of them.

Whatever, I've run a check of my database covering all meetings for the last six months, every meeting, every race, everywhere & the outcomes are somewhat different.

Comparing favourites on Good & Heavy track conditions only:

Heavy:
Races: 403
Winners: 120
S/Rate: 29.8%
LOT: 15.3%

Good:
Races: 6,387
Winners: 2,130
S/Rate: 33.3%
LOT: 11.7%

Observations & other tests of similar in the past indicate that what has happened in the last six months is an indicator of the long term performance of favourites on good & heavy tracks.

Chrome, I'm not sure it's the myth buster you claim it to be.
