So what do they do?
let a helium filled balloon fly up and shoot it down with an air gun?
where it lands is where they decide to put the split marker?

how meaningless.
how ridiculous.

how hard would it be to simply have every first split timed at a common 75 metre mark regardless of track or distance.

Maybe I send an email to GRV.
You think they will totally ignore me as usual Woof43?
