Just a thought, but by assuming Psysios Guide and description how it's supposed to work, does it mean that using "Shamrock's Ale" would double the existing chance of dropping a pink?

Let's say for example, Sanguine Longbow takes 500 bosskills to drop (just a guess!!!), because the chance of getting that pink is 0.2%. Using "Shamrock's Ale" would double that to 0.4% which means only 250 bosskills now? Am I guessing correctly (based on this expecting guide of course)???

One emma run takes around 4 minutes in a full group with all using 2* DMG elexir and a good tank . 250 / 5 groupmembers = 50 runs in total. 50*4 minutes = 200 minutes = 3 hour and 20 minutes of total farming = 7 * "Shamrock's Ale" + 2* DMG elexir. 25 * 7 = 175 Plat for one (more or less) Sanguine Longbow. DAMN.
