A quick question on setting up the ICO.
What is the opinion on how many decimal places to run the ICO at 1 or 2?
Obviously 2 is going to be more accurate but does it need to be that accurate or is 1 decimal place enough?27/04/2018 at 11:20 am #73645
1 decimal place. Otherwise it only allows you to adjust every 10m, so loads of +/- button pushin.
Wheras 0.1 adjustments are loads quicker.
As long as you are around 100m you’ll work it out from tulip and terrain. So many variation on exact metre-age depending if course was set by ‘wheel’, GPS track or through google-earth.27/04/2018 at 11:31 am #73646
It’s personal choice I guess but I run with 1 digit.
Yes it isn’t so accurate but you are never more than 90 metres out.
An example: Road book says there is a right turn at 43.75 km, when you get to 43.7 on your ICO, you know you are turning right in the next 50 metres… simples.
And let’s face it how often is your ICO and Roadbook absolutely sychronised, there’s usually a small margin of error anyway. I also go by the tulip first and the distance second, so a small error isn’t important if you are interpreting the tulips correctly 🙂
As Rob says It also means correcting your ICO to the roadbook is easier as you only have to change it 100m at a time not 10m.
i.e. if you are 90m out with 2 digits, you have to hit the button 9 times to correct, if running with 1 digit you don’t have to correct or at worst have to hit the button once!
I have seen pictures that show a lot of the top riders actually cross out the second decimal on their roadbooks for this reason. i personally wouldn’t as it’s helpful to know where in a 100m block the turn or feature is. That is does the feature appear at 43.00 or 43.90 i.e. do you need to be ready the moment your ICO gets to 43.0 or have you got nearly a kilometre still to go?

Thanks both for your opinions……noted.27/04/2018 at 11:39 am #73648
No problem, actually my ICO has been on 2 digits since I lent it to a mate for the Hellas and he changed it. Although it is a bit more useful that way for setting out the Road Book Capers! Must get round to changing it before I next race

I run to 2 decimal places – I guess it is personal preference. 2 decimal places has saved me from making a mistake when the navigation is particularly tight – say when there are two right hand turns with in a few meters of each other in a stage and only the correct turn is marked on the roadbook, this has happened on the R3, and organisers change the way they write the roadbook in stages, just to make it a bit trickier when under pressure !!!

I think I’ll have to try both ways and see how we get on!
