Calculate difference between two rows
Yes, measures are often the best solution, but there is a way to do it as a column as well: http://excel-inside.pro/blog/2015/11/05/absolute-and-relative-references-in-power-query/
I am not sure if I am reading your solution correctly.
I get this error: A circular dependency was detected: TableName[Difference].
So Difference is a new column with the result of row1 - row2 in the speed coulumn and so on.
Thank you.
Hi andysross
Please ensure that you create them as Calculated Measures and NOT calculated columns. That is why you are getting the error as described below.

I ended up using this method. Thankyou
Difference = var A = CALCULATE( MAX('table'[id]))-1 return If('table'[id]=0,'table'[speed], 'table'[speed] - CALCULATE(SUM('table'[speed]),FILTER('table','table'[id] = A)))
