It does look a little over-trimmed, from the shape of it. At 9 pounds, quite a bit of fat, and possibly a good portion of the point was trimmed off. Try laying some thick bacon on top on your next one if it looks over-trimmed. Or any kind of fat will work, like slabs of side pork, or salt pork. Not as good as the original fat, but it might help.
I go to 195 in the flat, 200-205 in the point. Since it looks like mostly flat, 198 might have been on the high side, but not that high. Your plan to check it at 190 next time sounds good. It should be floppy. If it's not, put it in for a few more degrees.
