Same timing as you but I'm on a big outdoor asphalt track and my ORCA 21.5 FDR is 3.3 (133F with no fan) and needs to be somewhere in the 3.2 to 3.1 (range probably with a fan). Ran by mistake a 3.0 FDR and it was fast but hot (170F) and still not as fast as the fastest. Was hoping the R1 would fix that but now I'm told it's out of stock too. Just my Bad luck.
