• Ace, thanks Sainos. That's really helpful. I've done all that when shifting the unit around except the battery removal.... i presume it's been under-reading all this time then :-)

  • yes, id presume that too, I went through a phase where I didn't remove the batteries and it was under reading chronically, probably to about the tune of 60w based on a time trial I did at the time. was tearing my hair out trying to work out what had happened to my legs!
