Template talk:Calculator/Light Healing

Basics
After some testing for a couple of days with several characters, vocations, levels and magic levels, we found a new formula that works for at least 6 different characters and is off by at most 1 point. (Level * A + MagicLevel * B) * C + D where of course Level is the players level, MagicLevel is the players magic level. A and B are constants, determined to be A = 0.4, B = 3.2. C is a constant depending on what spell used (at least, that is how we intend it to be), and D is a variable. As the results show so far, this number needs be rounded down. For the average hitpoints healed by exura we found C = 0.5 (0.50201 +- 0.00357), D = 8.6 (8.61267 +- 0.70719). So if your level is 30 and your magic level is 31, you'll get: (30 * 0.4 + 31 * 3.2) * 0.5 * 8.6 Rounded down, this gives a result of 65 hitpoints healed on average by exura. Tests have shown (54 exuras) that the average is about 65.16. I can give you more examples and numbers, but I hope you get my point now.

Minimum / Maximum
With our tests, we also calculated the minimum and maximum amount of health potions healed by exura. However, when trying to determine a proper formula for it (keeping A and B constants), we run into a problem. We can determine the variable D, however, not accurate enough. It's error is somewhere between 7 and 12, which is far too high to be accurate enough. Therefore I'm going to need more results to do some math with.

Determination of A and B
Craban (6th post) stated the following: For every 5 levels, you get 1 more healing, exura, exana mort, whichever you use. This means, A = 1/5 or 0.2. For B, we used the a sorcerer and a knight. Both level 140, but of course they have a different magic level. The sorcerer had an average healing of 155.71, the knight 49.44. The difference between this is 106.27. This difference is caused by 66 magic levels, therefore B is 106.27 / 66 = 1.6 (rounded to nearest number at 1 decimal). This also means the ratio between AC and BC needs to be 1:8. After some math by Griff, he found out A = 0.4, B = 3.2, C = 0.5 works pretty well for the average exura. Therefore, we are using those values as a 'base' for now.

Request
But as I stated before, I can't collect enough data on my own (unless I keep bugging my VIP list all the time..). So I have a request for anyone who wants to help us figure this out. Please cast exura's (40 at least, 60+ preferred) and wrote down your hp each time. You can go to the King in Thais to get you down to 1 HP (shouldn't do that on PVP worlds), then cast exuras. Make sure your normal regeneration has stopped, so we don't get those mixed in. Also don't heal to full HP, this will give inaccurate results. Any other results (exura gran, exura vita, other healing spells) are welcome to, but my focus is with exura right now.
