German Sum Introduction

I have invented a new clue type, I hope I have managed to keep this puzzle easy enough to nicely introduce this new constraint :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.

Normal sudoku rules apply.

German sum: A clue outside the grid gives the sum of all continuously adjacent digits with a difference of at least 5 up to (and not including) the first digit with a difference of 4 or less in that row or column from the direction of the clue. A digit in the first cell is always included in the sum.
For example, if row 4 is 728315469, then the sum would be 20 (7+2+8+3) from the left side and 9 from the right side.

German Sum Explanation:

Basically, you can imagine that you are drawing a German whisper line starting in the first cell next to the clue and ending in the last cell with the valid digit fulfilling German whisper line properties (adjacent digits have a difference of at least 5), and the sum of the digits on that German whisper line must be equal to the given total.
