Just count those s/km for 6, 60 and 600 km and compare the result. I hope You then understand.
If You want to be that precise then a spin on a corner will do the job. But I guess it doesn't matter if it is 10, 20 or 30 seconds for 600 kms regulating the pace.
On the contrary how do You know how You'll loose 10 seconds for 6km by pure pace, of course the chance is higher than for 600kms but it'll never happen because You're not super-human. It'll always be +- some seconds.
