DATA ANALYSIS

WARNING:
The following is a somewhat complex mathematics discussion. If that scares you skipto the nextsection,all will be revealed there!

EFFECT OF HEALING EFFICIENCY:
Data analysis consisted of plotting the healing results (without mods and with healing clothes) against Healing Efficiency, for each type of heal. Initially, the data was fit with a logarithmic function of the form: Heal Strength = A*ln(HE) + B. It was found though, that the equation did not fit the lowest HE, which was especially evident with Bacta Shot and Bacta Toss. Instead, the following equation was employed:

Heal Strength = A*ln(B*(HE+5))

note: this is the same as Heal Strength = A*ln(HE+5) + bwhere b = A*ln(b)

Best fit parameters:
Healtype A B R2
Bacta Shot523.8 0.168 0.999
Bacta Toss386.2 0.1840.998
Bacta Spray256.9 0.3580.984
BactaJab208.9 0.332 0.976
Bacta Infusion58.31.1060.761

This equation had an excellent fit to the data, for Bacta Shot, Toss and Spray. Furthermore, the equation makes sense, since without a number added to HE, the equation blows up at HE=0.If the equations were meant for heals to be zero at HE=0, thenB shouldequal 0.2. The fit B values were all near 0.2, except for Bacta Infusion, which had little data.

Not enough data was available at low HE to see if this was the best equation for Bacta Jab and Infusion. For consistency sake, though, the same equations were used. The data fit for Bacta Jab and Infusion arent very good either, a situation that could be remedied with more data.

The other striking point is this data is that there is no difference between heals at different skill levels. They all fall along the same line, with the only difference affecting the heal being the amount of Healing Efficiency. Consequently, odd situations arise, where a Master Doctor with minimalCM skills, can out heal a master CMon Bacta Toss or Spray.

EFFECT OF ENHANCERS AND DROIDS

Analysis ofthe data above shows that both droid and enhancers work by adding a constant amount of healing, regardless of skill level. It is expected that the strength of the enhancer and the rating of the droid affect the heal, but this was not tested. Below are the increase in heals when using enhancers and droids.

Healing Increase with:
Droid Enhancer
Bacta Shot+441 ---
Bacta Toss+331+579
Bacta Spray +263+445
Bacta Jab +215+382
Bacta Infusion +10 +17.3

Clearly, the effect of droid and enhancer on Bacta Infusion is much, much smaller than the others, leading me to believe that this is broken. Because the healing increase is constant regardless of skill level, enhancers and droids have a HUGE impact on low level medic skills, increasing them up to 300%!

Ibelieved that the enhancers and droids, work as a multiplier of the Healing Efficiency (this would give a constant increase regardless of level). If you back calculate the multiplier to healing efficiency cause by the droid, using the best fit formulas above, it is quite consistent at 2.2 to 2.8 (average around 2.5x multiplier). I couldn't find consistency of how the enhancers work, but I suspect it is also a multiplier to healing efficiency.

From the Medic and Doctor Forums...

Here is a better listing for each Level of the Medical Module, when used with Bacta Shot.

Level 1 Medical Module / 55 Rating = 200 point increase

Level2 Medical Module/ 65 Rating = 250 point increase

Level3 Medical Module/ 75 Rating = 300 point increase

Level4 Medical Module/ 85 Rating = 350 point increase

Level5 Medical Module/ 100 Rating = 400 point increase

Level6 Medical Module/110 Rating = 450 point increase

This appears to be across the board, regardless of the medics/doctor skill.

These numbers are based on results from a 0004 Medic anda 0040 Medic. Both tests showed the numbers to be in the same range for each level of medical module.

Nice addition! Any chance of repeating the test for the other heals?

Omg test with some +25 clothes please

And some healing eff foods

Thats why the equations are there. Plug the HE including the food & clothes into the equation and solve for the expected heal.

If you want to post a few scenarios, I'll use it as an example. I would need your base HE and the HE of the mods and what skill you wanted to use.

good job!

one problem - the equasion you got from using excel is close but it suggests that as there is still some discrepancy the actual equation used is different. i checkeda basic formula y=ln(x+2) in the same way and the result it gave was in the order of y=0.85ln(x) + 0.8 (i'm guessing a little here) but it demonstrates that excel cannot quite get the correct forumula - just a basic ln one instead. be great if we could find a more complex program to plot results against a wider range of formulas

PS ty for the help earler
