Tying people up and Grapple.

As per grapple rules, you have +5 on grapple checks after grappling.

(If your target does not break the grapple, you get a +5 circumstance bonus on grapple checks made against the same target in subsequent rounds.)

Tying someone up is a check made with -10, if you skip pinning them.

(If you are grappling the target, you can attempt to tie him up in ropes, but doing so requires a combat maneuver check at a –10 penalty)

So, does the -10 here include the +5 already, or does it not? (thus you only take -5 on your attempt to hog-tie your victim).

I'm leaning towards it does not include the +5, but it's rather late and I rather want a decent chance to tie people up right quick.

It should not have the +5 already included; since you are maintaining you would add the +5 unless something tells you otherwise. Nowhere in the grapple text does it tell you not to add in the +5 when tying an opponent up.

Also, a grappler might be tying up an opponent in the same round that he began the grapple in, in which circumstance, he would not have earned the +5 circumstance bonus.
