Guildford City Race

Would a pedestrian footbridge with a roof on it and ramps (not stairs) for access at either end not have been mapped essentially the same ?

[Scott]

It could have been, although personally I would probably have mapped such a footbridge with ISSOM 512.1 Bridge. In that scenario I don't think knowing that the bridge has a roof is particularly important, and mapping it with 526.2 Canopy would create more confusion than it would save.

where do we draw the line on voiding legs?

We draw the line when significant numbers of people are significantly affected by something unfair.

As I wrote in CompassSport recently, there's a neat way to tell this if the results are in Winsplits. If there's a slew of red (i.e. errors) on a particular leg, and it is unrelated to finishing position (i.e. ability) then that leg is testing something different from the rest of the course, and any planner with an interest in improving their planning should look at what it was. Usually there's an explanation: maybe it's a steep hill, maybe it's a cunning routechoice, maybe you even did something clever without recognising it . But if that leg has a known problem then it's just generating random times to add to the time taken on orienteering sections, and taking it out is a better representation of who orienteered well.

Judging by that theory as the results aren't in win splits I reviewed the split times and the spread for 4-5 seems to be approx 1-2 min difference across the majority of runners - which seems reasonable for a route choice error. Same ratio applies to 7-8 so should that be voided?

Isn't the non-use of legitimate/compulsory crossing points a very old chestnut indeed, for long plaguing ISOM events as well as ISSOM ones. If you want people to use them, put control markers at/near(or under) them - get your route choice excitement elsewhere- there's usually plenty of scope.

From what I've heard the controller discussed the cross-hatching and crossing points with some of the grade one controllers at the event.

It has nothing to do with the spread (even though that's bigger on the shorter leg 4-5). On 7-8 peoples split times match very well with peoples overall times, on 4-5 they dont. Winsplits would show this.

Rankings?

Now on the BOF site.

Not just for the Guildford City Race, but also for the mass start trail challenge event the following day. I thought mass start races couldn't have ranking points? Even disregarding the mass start issue, it seems weird to award orienteering ranking points for what was essentially a track and path run.
