Same set up on the sheet - same data periods etc
Jockeys - Most significant

What struck me here with the jockey data was that the 2016 data check mostly held up and stayed in the realms of positive. Ryan Moore has a 50% strike rate in this period , but a very small sample.
Dettori with the largest jump in Win % when he only has the one ride of the day from 205 runners (just over 3% of rides) - market has them covered though by the looks of it.

Some decent jockeys on there - interesting to note that 2 of the better ones - James Doyle and Adam Kirby both turned their 2016 data around - Doyle by 13.29% in 2016 increasing his "Single mount" win % to 33% from an overall low of just under 11%.
Brian Hughes at the bottom there strangely for a jockey who since the turn of 2018 is riding at a 24% strike rate from over 140 odd runners and normally 13% to over 16% depending on what period of data you look at - yet overall the data shows when he has just the one mount the strike rate drops to around 7% overall from 479 rides.
