Just as I thought I was starting to understand ECE's I've got confused…
I'm looking doing a 400 ECE onto a 600 calendar BRM. The 400km ECE link gives you 28hrs + 40hrs for the 600 = 68hrs.
A 1000km calender BRM or a 1000km DIY is 75hrs.
Am i looking at this incorrectly, or is there really a 10% time difference ?
