Mana reservation problem - can't run auras

Hey guys!

I have a problem, with mana reservation. I hope you can help me.
This is my passive tree:


I have 16% reduced mana reserv, and have 2 lvl21 reduced mana gem.

I would like to run 2 60% and 2 25% auras, but I cant.

If my math is correct, I have 16% reduced reserv in total, and 30% less reserv connected to each aura.

60% * 0,84 * 0,7 = 35,28%
60% * 0,84 * 0,7 = 35,28%
25% * 0,84 * 0,7 = 14,7%
25% * 0,84 * 0,7 = 14,7%
SUM: 99,96% reserv, but I can not run them.

Where is the flaw in my theory?

Thanks for your help in advance!

You're leaving out rounding.

60% * .7 (mana multiplier from RM gem) = 42%
42 % * .16 (reduced from tree) = 6.72%, rounded to 6%
42% - 6% = 36% reservation required for each 60% aura.

I think they only allow you to add the reservations together for the case of running 1 60% and 1 40% aura with no reductions so that you can run both together. Otherwise you have to calculate and round each individually.

Thanks for your help guys!

It helped me to solve this. I forgot the rounding, and the fact that it is rounding always upwards.

It means I have 2 times 36%, and 2 times 15% and it is 102% in sum. I'm ok with the 15%, but I have to decrase the 35,28% under 35%. All I need is a lvl22 RM, and I can achive it by vaaling a shield/boot/glove with a +1 gem lvl mod.

After tons of currency spent I made this:


So now I can run all my auras, and I'm happy :)
