Aw C'mon Pinky,
At the speeds at which you and I travel these days, it matters not whether you add a reference after the 'magic numbers', COZ, by the time you've finished it all, you are going to be a bit closer, and if I am the one in your way lookin' for ya, I won't care much if you're not 'xactly' 31.16 recurring, as long as I see you 'somewhere' at around the 30 nm mark OR SO, I'm happy...!!
Couldn't resist the 'tough'......
Cheers, LOTS of 'em....
