Changing a few things, accounting for false positives
(assuming worst case and rounding up for case 2a,
rounding down for 2b)

> * # Changes needed in 2a = row 1 + row 7 + row 8 + row 9 + row 10
>                         = 34 + 80 + 10 + 3 + 3 = 130
> * # Changes needed in 2b = row 1 + row 4 + row 5 + row 6 + row 7 * (~3)
>                         = 34 + 80 + 141 + 74 + 85 + 240 = 654
> * # Changes needed in 2c = Changes in 2b + some more

becomes

* # Changes needed in 2a = row 1 + row 4 + row 7 + row 8 + row 9 + row 10
                        = 34 + 80 + 141 + 10 + 3 + 3 = 271
* # Changes needed in 2b = row 1 + row 4 + row 5 + row 6 + row 7 * (~2)
                        = 34 + 141 + 74 + 85 + 160 = 494
* # Changes needed in 2c = Changes in 2b + some more
