In all these calculations u forgot power of visa card.
14780 Total Ether / 51.5 Average per day = 286.9 days to gather enough ether for r110. So pretty much 287 days total
287 / 30 = 9.5 Months
9.5 months / visa card = 2 clicks( about 3-4 seconds)
Be good and dont forget holy power of visa! Allilua
