Hi - As an analyser I see things like the run at Menangle 5/2/21 all the time. The runs prior at Bathurst were much slower pace.
See below after I have applied all required factors to the runs to convert them to Menangle times:
Date Location Mile First Last8 800-400 400T
05-Jan-21 MEN 114.7s 57.5s 57.2s 28.7s 28.5
26-Dec-20 BAT 117.6s 61.5s 56.2s 28.4s 27.8
16-Dec-20 BAT 117.8s 62.7s 55.1s 28.2s 26.9
The times above are without including actual distance run and that brings them closer again.
Noting that on average horses times over similar distance between Menangle and Bathurst will decrease by 1.5 seconds and last 800m by around 1 second. Yes this race was run quick comparatively (Mainly due to the fast first pace) and this horse was not tried at this pace previously. Given the advantage of leading I didn't see it is a massive discrepancy. If you chart first vs last800 you will see what I mean.
In saying all that I had no idea Pacman Hammer would lead this race or that it would be run at that speed so my pre-race analysis was wrong. Also note I see it a lot when a horse runs a much quicker race that it will gallop next start. Happens regularly but you can't bank on it.
Hope this helps explain it a little bit.
