I think that I might be off, but I am not sure, where I made a mistake, even though I used an online calculator.

I am trying to calculate the decreases for the lower half a sweater sleeve, from the elbow to the first knuckle of my thumb (yes, I want the sleeve to be very long). Are these calculations correct?

At the elbow (where I am now in my knitting) I have 59 stitches

My gauge is:

5 stitches = 1 inch

7 rows = 1 inch

on 5mm double pointed bamboo

distance from elbow to first thumb knuckle is about 15 inches

distance around hand (I measure area around thumb nuckles) is 9 inches

So I have to reduce 2.8 inches or 14 stitches (i.e 2.8 inches x 5 stitches) over 105 rows (i.e 15 inches x 7 rows)

According to the Magic Number Calculator:

1 st at each end of every 15th row 7 times (105 rows = 14sts)

Total stitches increased/decreased = 14

Stitches increased/decreased each side = 7

Total rows knitted = 105

60

75

90

105

After Row 105, there are no more rows to decrease. What should I do?

Any advice on how to get this increase/decreasing calculations figured out would be great, as I have had to rip this sweater out countless times because of problems with shaping and I think that I would be a much faster knitter if not for this.
