La Bague's rating is wrong IMO, and was achieved running against a similar class of horses that Laurina has beaten, every time she has stepped up in class she's been found out, the excuses for this are now boring.
Her best piece of form was beating Jer's Girl and midnight tour, earning her a 9lb hike, she got a further hike for hammering lower rated horse next time.
Jer's Girl has not got close to winning a race since and has been beaten out of sight in handicaps, although she finished ahead of bague in the mares,
Midnight Tour, who was beat four lengths by Bague that day, ran her best ever race in the mares, but was beaten by woolstone one in the race before the festival.
Laurina beat woolstone one 47l jogging at punchestown.
Now form is hard to take literally for a myriad of reasons, and it's up to the individual what you choose to follow, and ignore.
But in a nutshell.
Laurina's rating definitely may be wrong, but equally may underestimate her ability.
Pretty sure La Bague Au Roi rating is wrong.
