I still need another 39 hours to get over my biggest 'training' year of 2010 and only 15.5 days to do it. I don't think I'll quite make it.
Not surprisingly my three biggest years are 2010, 2011 and 2015 respectively (although I expect I'll get over 2011 with just 5.5hrs to go), all XPD years. Probably doesn't help that XPD in 2010 took us 48hrs longer than this year but then it took an extra 31hrs in 2011! Mind you, 2010 was also the year I drove a handlebar through my knee and spent about 1.5 months doing nothing (with XPD in the middle of that).
20 hours or so off is what I would call "Near enough" in the scheme of things. Relax, you're consistent!
Well my XPD years (2010, 2011 & 2015) range from 976 to 1010 (or will do in another two weeks' time) and non-XPD years (2009 & 2012-14) range from 748 to 842, with the two higher ones being WMTBOC years. What will happen next year with both the WMTBOC and XPD???
Actually I've logged more MTBO in 2014 than 2012 (Hungary year), oops. Probably all that mapping I did somewhere.
Your 2013 ruins your declining pattern anyway and I don't know what's up with 1997.
2013 I label as 'outlier due to injury' and can dismiss. 1997 I haven't finished logging yet - I wanted to find out what a single representative year from 1994 - 1998 was actually like!!
