Calculate sub-block totals (b) and replicate totals (R).
Calculate the treatment totals (T) and the grand total (G).
For each treatment, calculate the Bt values which is the sum of all block totals that contain the ith treatment.

Treatment 5 is in block 2, 5, 10, 15, and 20, so B5 = 616+639+654+675+827 = 3411.
Note that the sum of the Bt values is G x k, where k is the block size.
For each treatment calculate:W = kT – (k+1)Bt + G
W5 = 4(816)-(5)(3,411)+13,746 = -45
