Ok, very good to read that you train
James Bush very well.

I already spotted him in my previous season as Australian NT manager,
that was in season 15 when James Bush entered the game as 19yo.
And immidiately I gave him an xp place to make his debut for Australia in NT race 2 :
https://cyclingforfun.org/smf/index.php?topic=710.msg25786#msg25786 As you can read ; the other 2 xp places in this mountain race were for Nobby Licuria and Jasper Blair ;
what gives a good indication how very impressed I was by the 19yo James Bush.
Nice to see that he turned out to be the nr1 u23 DT ánd even more important ; that he has an excellent manager who trains him very well.

No doubt you know this, but I mention it anyway because it can be interesting to other, less experienced managers with Australian talents ;
keep in mind the 0,02 automatically u24 bonus per update.
What is 91 x 0,02 = + 1,82 point automatically per season on every skill.
A now 22yo will gain 1,82 (next season) + 1,34 (the remain of this season) = + 3,16 point automatically before his 24th birthday.
So, the current hill skill of James Bush is excellent already and he does not need to train that anymore due to the u24 bonus.
Only at the end of next season he needs maybe zero, or most likely just a few hills trainings to get to the important 100 hill skill.
Good luck with the downhill and technique trainings !
And very nice that James Bush has good flat as extra, what makes him suited for all different future NT hills races.
Of course, this good flat skill is in your team also an essential extra, to ride the classic hills races AGR, FW and LBL.
