== Distance numbers for my Umbria 100

This is probably going to be completely boring for anyone who isn't me.
But I want to write it down somewhere, so it might as well be here.

* bought the bike in late April of 2006 (I have the exact date somewhere)
* put the bike computer on about May 28th 2006 (ditto for the date)
* as of May 28th 2007, I believe the odometer was about 5550 km (it was
  at least 5500 km, and I believe it was a bit more).
* at the end of my bike ride home from gaming on April 13th 2008, the
  odometer hit its 9999.9 km max distance. Some amount of distance was
  lost.
* Monday April 14th: +4.2 km on the commute to work, +some unknown
  distance commuting to dentist's and back (I think 4-6 km).

  Computer totally reset in the afternoon, before my commute home.

* May 28th 2008: during the day at work, the odometer read 723.46 km.

* Jan 4th 2009: before riding the bike in 2009, I reset the odometer.
  Pre-reset it read 4794.2 km. I carried over the April 14 2008 wheel
  size of 2170 mm.

* May 29th 2009: just at the departure from work, the odometer read
  1867.5 km and I had biked 5.229 km that day. (I was just at the
  start of St George, so that's about right.)

Two balacing factors:
* this includes some amount of distance from walking the bike, especially
  on daily commutes (where I walk it a few hundred meters inside the building).
* the tire size is set slightly low. I believe I set 2170 mm (700x30 in the
  manual) versus 2180 mm (theoretically correct for 700x38 according to
  [[here http://www.chainreaction.com/radarcomp.htm]]), but I may have
  set lower.

  (Did I set it to 2070, the listed 700x18 size? I may have.)

  Update, June 9th 2008: I found my [[gear calculator Umbria100Gearing]]
  program, dating from May 20th 2007, and it uses a wheel size of 2155 mm.

At the April 14 2008 reset, I put the wheel size at 2170 mm. This
appears to be roughly correct within a cm or less, based on rolling
tests at work (where there is a set of 1-foot floor tiles nicely lined
up).

=== bike computer functions

* press left and right for 4 seconds on either display and you get to
  total reset. Doesn't seem to flip to anything else.
* press left for long enough on the clock/odometer (second screen) and
  you can reset the odometer.
* somehow I managed to get to set the time without totally resetting
  the unit, but I am not sure how any more.

  I've now reproduced this. Once the odometer is high enough, press
  and hold the left button on the second screen to change the clock;
  it may matter that this was shortly after a trip reset. \\
  (At least I assume it requires the odometer to be high enough.)
