Same basic noughts and crosses approach to framing the markets, PP, with some minor changes around giving less and less chance to outsiders. I don't have any data to back it up, but is seems that more and more race winners come from the top of the market.
The actual individual horse ratings have probably developed a bit, but I certainly still focus on assessing Class and Race Suitability as the key factors in these ratings. So far, I'm also a bit more selective about whether I fire the gun .. I'm betting on less races for sure.
A few things have changed though with people using Incremental Velocity Ratings (nice name), speed maps, track walk data and the like more and more, rather than the old Cliff Cary and Don Scott approaches that I grew up on.
PP, I'm happy to report that the stats from my first 28 bets back are better than ever. I hope that this nice start continues. I'm enjoying it!
