Ok I am going to give you guys the easy way to solve all of the individual formulas.
If you are not at stage 5 you can use the crushed jurpleberry method. Check out any chart for which properties you need. Jurpleberries have the property that each thing that you do to them raises only one stat to a max of 180.
This site has both the chart and the method :

But I will restate it. Take 1 (or 3) gram of Jurpleberries. Then take another and another and another until you have enough jurpleberries to make up the weight of the potion. Then follow the following:
For <u>enchantment</u> burn them until you get your desired number
For <u>conjuration</u> crush them until you get your desired number
For <u>divination</u> soak them until you get your desired number
For <u>power</u> dessicate them until you get your desired number
If you need a combination...say enchantment and power then burn the berries and then dessicate them.
This works very well once the jurpleberries are available.
However this is not enough for the last step where it asks you for +300 and the jurpleberries go up to only 180.
This is where baabaa wool really helps. Just choose the method does not have a -1200 penalty for either of the stats.
For <u>enchantment</u> burn, crush, or soak to the max (dessicate will cause a -1200)
For <u>conjuration</u> burn, crush, or dessicate to the max (soaking will cause a -1200)
For <u>divination</u> burn, soak, or dessicate to the max (crushing will cause a -1200)
For <u>power</u> soak, crush, or dessicate to the max (burning will cause a -1200)
As an example if you needed a 300 in divination and power you would want to crush or dessicate the wool.
If you want to figure it out the long way I suggest setting up an excel spread sheet. So for instance if you want to use 4 different ingredients each of three grams you can set up the excel this way:
A B C D
1 Ingredient Stat#1 Stat#2 Grams
2 #1 ### ### 3 ^
3 #2 ### ### 12^^
4 #3 ### ###
5 #4 ### ###
6 Total * **
7 Final + ++
* the formula should be =(b2*d2)+(b3*d2)+(b4*d2)+(b5*d2)
** the formula should be =(c2*d2)+(c3*d2)+(c4*d2)+(c5*d2)
+ the formula here should be =b6/d3
++ the formula here should be =c6/d3
^ this is the number in grams of the ingredient
^^ this is the total weight of all ingredients combined
### This is resulting number from the chart mentioned above.
Personally I used the first method and prefer it.
