T1 at Harlow 415m is THE structural advantage — the rail saves ground through every bend and those savings compound over 4 turns. Comer Canal is a moderate Fader (EP55, CS39) rather than an extreme one — CS39 means he decelerates through closing stages but not catastrophically. From T1, the ground he saves on the rail partially offsets the fading tendency. P49 is competitive (1 point off the joint leaders) and form of 41→46→39→34→51 shows recent improvement to 51 — the highest single run in the field along with Steel Duke. The concern is the erratic nature of that form — 41→46→39→34 was a decline before the 51 bounce. But at A7 where the field quality is modest, P49 from T1 with a moderate Fader profile is a strong structural play. Carter at 14% is cold but the T1 advantage transcends the trainer signal.
