I'm no expert & I'm probably totally wrong but firstly, well spotted, I've read the RNS a few times & never picked it up, the only thing I can offer is modern machinery uses the metric measuring system & I haven't a scooby how old the rig is, with this in mind I am pretty sure if the rig hails from the USA, then again I am pretty sure they still widely use feet & inches, or as my mentor used to say when I was an apprentice 'English' GLA
