Yellow line second 'E' badly drawn. Here are two possible calculations one real and one theoretical.
Drop of first "E" $11,065 - $ 10,210 = $855. Therefore drop of second "E" is real rise of "B" to $9,177 - $855 = $8,322. Alternatively, rise of first "B" was $11,065 - $9,280 = $1,785. Therefore, theoretical rise of second "B" was $7,240 + $1,785 = $9,025. Then theoretically second drop "E" $9,025 - $855 = $8,170.
