1. A method for optimizing lumber derived from a log, the method comprising the steps of:
debarking the log;
cutting the log to provide a plurality of boards;
scanning the plurality of boards to determine a first warp stability for each of the plurality of boards;
sorting the plurality of boards based on the first warp stability;
scanning the plurality of boards to determine a second warp stability for each of the plurality of boards;
selecting a lumber upgrade process for each of the plurality of boards based on the second warp stability;
processing each of the plurality of boards based on the selected lumber process; and
planing one or more of the plurality of boards after the board is subjected to the lumber upgrade process.
2. The method of claim 1 wherein the lumber upgrade process is edging of the board.
3. The method of claim 1 wherein the lumber upgrade process selected is also based on knot properties.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.

R2 and R4 are an alkyl or aryl radical having 1 to 30 carbon atoms,
R3 is an alkyl or aryl radical having 1 to 50 carbon atoms which optionally contains heteroatoms,
A is an alkylene unit having 2 to 6 carbon atoms,
x is a number from 0 to 10,
y is a number from 0 to 10,
n is a number from 0 to 100,
k is a number from 1 to 100,
R5 is an acid group or hydrogen, and
m is a number from 1 to 500,
with the proviso that (y+n) must be at least 1.
2. The process of claim 1, in which R5 is the radical of a dibasic acid or tribasic acid.
