This kind of "feature" is irrelevant for me in the decision if to buy the
program.
If I can translate the score to the real score than it is enough for me even in
cases that there is a bug.

I guess that most people expect the same as you and me but I can speak only for
myself and not for the majority.

I do not think that this will be a reason for people to decide not to buy tiger.
