Track lengths

[TSR]

Now this has being a bit of a bug bear of mine. I have notice over the years that the TV coverage have added extra corners & length to our race circuts. To make a point of this the TV says that Bathurst has 23 corners and is now 6.23k long.
Now I have googled earthed Bathurst and counted 21 corners and since 1987 the track length has always being 6.172ks. So over the last 2 years were did it grow?

And Bathurst is not the only race track that the TV has added extra corners.

I know this is a small thing and I could be wrong but WHY does the TV add extra corners for the sake of it.

My experience is that the corner numbers are those used by FIA circuit plan. In these situations some corners may have two turn numbers where you may consider is one corner. Circuits are also measured at each inspection by a measuring wheel a set distance from the track edge, it does not take much reconfigured work to get some variances.

Perhaps this is the case here,

Wrong, it was 6.172km up until 1987. When they added the Chase, the extra distance made it up to 6.213km, which is what it has been since 1987 until the present day.

It has had 23 "corners" for ages when it went from having 35 marshals posts (1-35) to the current corner and decimal numbering system following the FIA rules.

I started marshalling there in '91 under the old scheme but it changed at some stage during my 10 year stint.
