Heal Spell, need help with mechanics Options

[Gronin]

We are returning to Shadowrun after a very lengthy abscence (lots of 1st Edition and some 2nd Edition) and my attempts to search the forums haven't worked so I am looking for some help with the mechanics of 4th Edition Heal spell.

The problem we are having centers around the drain value and just what is meant by "damage value". Is Damage Value the amount you chose to heal or is it the value of the wound you are attempting to heal or is it the value of all the wounds that individual has taken to this point. (the last begs another question - is each wound a character takes considered a seperate wound and thus each "wound is healable once- by magic)

The example that came up in our first session was as follows - a character got hit for 9 points and the mage tried to heal. He had 6 successes on his magic test (which was reduced to 5 as that is the max allowable as his Magic is only at 5). He used all 5 successes to reduce the wound. Does this make the drain 7 (damage value -2) and require a time for permancy (sustaining the spell) of 14 combat turns?

OR as was suggested by one of the other players could he take his 5 successes use three of them to reduce the wound by 3 and 2 of them to reduce the time down to 1. In this case drain would also be 1 as wound value would be 3 and drain value would then be 3 - 2 or 1

Thanks in advance for any help
