Strength value of 8 does not allow me to raise combat technique over 6

[JoveToo]

Describe the bug
If my Strength is 8, I cannot raise it over 6 (the default).
If my Strength is 9, I can raise it to 11, which seems correct.

To Reproduce

Set a Strength value of 8.
Try to increase Combat Technique rating.

Expected behavior
I expect the Strength rating to be able to raise to 10.

Environment (please complete the following information):

Linux, 1.4.2
