Ok so I am not sure if its my “new” math that is making this really hard to figure out or if the author couldnt do math themselves. OK sorry, however it said for me to do the math so I did and this is what I found.

If short-sighted people make 20 jumps for 6 million ISK which takes an hour to do. Then the trading guru makes 3 jumps for 2 million ISK which takes 45 minutes to do.

So here is the math. Very simple really
hour 1 = 6 mill isk
hour 2 = 6 mill isk
hour 3 = 6 mill isk

For a total of 18 million ISK for a total of 3 hours time(the guide says this is WRONG)

45 mins = 2 mill
so in 3 hours I could make 8 million ISK.
I am totally confused! Why would I want to not waste 15 minutes (45 mins compared to an hour) and lose over 12 mil ISK?!?!

Now maybe the numbers should be more like 2 jumps takes you 15 mins and makes you 2 mil, so that in 1 hour you make 8 mil compared to 6 mil. But NO WAY is the math correct with the numbers provided.
