Where are those averages available?
You’re looking at it from a Poole pov, I’m a neutral, Kyle Howarth and Scott Nicholls are better than Zach Cook, both average wise, and just from watching them.
Zach Cook scored 5pts at Plymouth three times, 4 at Edinburgh, 4 at Berwick last season, those 3 teams weren’t amongst the best in the league (slightly harsh on Edinburgh from myself, but it was a 3 horse race last year really). He was at Berwick before the signings of Morris and Jeppesen and only managed to beat Smith, his 4 other points came from falls and retirements. At Edinburgh he beat Grahn and Starke, his other two points were from retirements. This was all whilst riding at the considerably easier number 4 position. Compare his scores to Kyle Howarth, who’s lowest score was 6, at Poole, and a bunch of 7’s, but ultimately far more consistent around the tracks, at number 5. Scott Nicholls scored 7+3 away to Edinburgh on his comeback meeting, a poor score of 3 on his home debut then managed at least 9 thereafter.
