Another BILL JAMES mathematical doodle he invented to project an estimated
chance a player had to acheive a certain total goal; used to be called
"Favorite Toy."

6,857 TB to pass Aaron in #1 TB 2,856
3-2-1 Weighted "Avg./Yr." from previous 3 years; 2008 number is weighted
'3', 2007 is '2', 2006 '1'; then summed and divided by 6 to get an Average
per Year on category.
Yrs remaining = (42-age) / 2
[Pujols currently projected to quit at 35; "Yrs." will naturally get older
as he ages 1 yr for every 2 he plays]
Likely Percentage to achieve = [ (Avg/Yr. * Yrs.) / Target number] - 0.5
A conservative Percentage at the least, considering the Yrs. remaining when
young (ex., 28) are automatically extended as the player ages, see table
below.
