I didn't say it was, the discussion (since deleted) on facebook suggested it might be. As we know, every field is different, even the most rigorously laid out training field differs from the event field(s). At least in Pro/CPL there is only usually one event field to contend with.
I agree, the Euro based teams will have had the chance to grind for 4 weeks on the layout, whereas those US players & teams will have one event on a similar field and maybe a couple of weekends on a facsimile, but without the M & mini Ms it won't be the same.
P.S. feel free to lift the overlay if you wish
