30 Year Plan to Clear-Cut

Yr 15 - First thinning
Pulpwood 24.1 cords x 2.68 tons per cord = 64.58 tons x $10 = $640 per acre.

Yr 23 - Second thinning
Pulpwood 1.2 cords x 2.68 tons per cord = 3.22 tons x $10 = $32 per acre.
ChipNSaw 7.5 cords x 2.68 tons per cord = 20.1 tons x $18 = $360 per acre.
SawTimber 2.1 MBF x 7.5 = 15.75 tons x $24 = $378 per acre.
Total ... $770 per acre.

Yr 30 - Clear Cut
Pulpwood .6 cords x 2.68 tons per cord = 1.61 tons x $10 = $16 per acre.
ChipNSaw 5 cords x 2.68 tons per cord = 13.4 tons x $18 = $241 per acre.
SawTimber 12.6 MBF x 7.5 = 94.5 tons x $24 = $2,268 per acre.
Total ... $2525 per acre.

Total ... $2786 per acre.


Something appears to be wrong with the table.  I find it hard to believe that waiting two more years ... yr 23 to yr 25,  causes the total tonnage to go from 38 to 65 tons.  Can not be correct.  Double back and look at this.
