Given that all of his form has come in small field races that haven't been run at a particularly fast gallop, this will undoubtedly be something of a new experience for him
Again I'm not sure there's too much evidence to support this notion. To my mind he's got both bases covered regarding pace.
For the setting of standard times Graeme North will have us believe that any winning TS within 7Ibs of the winning RPR is evidence of a true pace within the confines of the respective ability. In winning his grade 1 at Navan he ran a TS of 150 and an RPR 153, that he's recorded these figures at the top grade available to him is a pretty good indication that he can sustain a gallop, and one should be even more encouraged that he did it at 20F's. Stamina doesn't look like being an issue, neither does speed. If he wasn't able to susatin a strong gallop, and hadn't been exposed to a strong pace, he wouldn't have been able to post a TS that close to his RPR.
Personally, I think he repeated the dose in his grade 2 win at Punchestown. On this occasion he was given a TS of 112 and an RPR of 151.
There were 3 chases, 3 hurdles and 1 cross country race run on the card and my own figures adjusted to par indicate that the chase course was riding faster than the hurdle (I omitted the x country)
Chase
-4.00
-5.00
-5.00
Hurdles
-8.40 (Mikael)
-9.00
-10.33
At raw mile aggregates you get a similar picture;
-8.20 (Mansony - chase)
-10.60 (Forest Leaves - chase)
-10.60 (Colmanstown hope - chase)
-11.60 (Mikael - hurdles)
-13.70 (Socerer - hurdles)
-15.33 (Dashing George - hurdles)
Based on this, I'm prepared to suggest there's a full going description difference between the two courses, and if they're split with different track variances applied, then Mikael D'Haguenet has run very fast for a second time. If they variance is calculated across the card, then it's only a moderate performance. This time the performance was put up at 16F's suggesting that he has pace here too.
At the other end he's got two slow TS performances. One of these came at Navan again, in a madien hurdle where he recorded 27 and an RPR 133. This suggests a slow pace which he's won by using a decisive burst of acceleration to settle the issue. He beat 'What you cracking' by 4.5L's with a potentially telling gap back to third of 18L further. Interestingly, the much touted Cousin Vinny also beat 'what you cracking' in a novice hurdle and recorded slightly lower, (but comparable) figures of TS 14 and RPR 123. Cousin Vinny gave 2Ibs to the defeated horse but only put 3L's between the pair. This indicates that in the autumn at least, Mikael D'Haguenet, had run and won a very similar race to Cousin Vinny through the runner up, and on both occasions and the winners are very likely to have done so by showing the same level of acceleration off a slow pace. Cousin Vinny is of course now favourite for the Supreme (but can he win off a sustained gallop
) The third placed horse was considerably nearer,(6L's) but this could be indicative of quality and depth of opposition as much as it would be the burst of speed that was used to spread eagle the respective fields. 'What You Cracking' ran to the same level against both, and at level weights there was nothing in it.
Finally Mikael D'Haguenet provided another demonstration that he can come off a slow pace with a burst of speed at Naas when he won a Grade 2 at 20F's this time by not having to rely on sustaining a gallop. He nothced a TS of 31 and an RPR of 153.
In short he's won two graded races at 20F's off both a fast and slow pace, so the biggest reservation would lie with the fact that he's unproven on a faster surface. Provided this presents no difficulty then I'd rate Amanda De Cadenet as the most likely winner.
