I should point out that there is some (small) element of randomness associated with the increases/decreases in form. Also, while form is reported as an integer (that is, as an adjective), it is stored as a decimal number. The player who increased might have gone from x.9 to (x+1).0, and the guy who dropped, from y.0 to (y-1).9.
