Special ability adds to market value ? multiple positions?

[Toxcatl]

It doesn't change his wages or value on his player contract sheet, neither extra position nor special ability.

Well, stricktly speaking, it does, at least a new position. Not very much though:





I was carefully training the last position point, but he accidently got 1% to a skill anyway. I don't think that 1% gave 100k to the market value, or did it?

In a day or two I'll check SA. I promise to be even more careful =]
Any additional information on the subject would be appreciated.
