Thanks for clarifying! Let's walk through the rules here, to see if it clears things up for you.
Rule 1 - pretty straight-forward
Rule 2 - Again, easy to diagram/understand
Rule 3 - G 10 (and 10 G); also note there is exactly 1 G. This also means that 2 can't be G (because it is 9).
Rule 4 - 8 O (and O 8)
Rule 4 also means that sites 4 and 5 both can't be 8 (because of rule 2).
Rule 5 - This one is trickier. It looks like 3 could be 9 or 10. However, 4 is not 8 (see above), so 3 is going to have to be 10, and 4 is going to have to be 9. 1 cannot be 10, which also means it cannot be G. If 4 is 9, it can't be G, and it already couldn't be O, so we know 4 has to be F.
I think what might have happened is that you might have had a mistaken reversal of Rule 4; note that it is 8 O, but NOT O 8. Similarly, G 10 but NOT 10 G. Getting that mixed up could cause the issue you had with thinking there were more limitations than there actually are. Take a look, and see if that helps. If not, see if you can walk us through how you got to F 9 and O 8.
