Comment(by madi):

 Hello Markus,

 Thank you for that! Actually I still find that the results produced by G7
 are different from the ones produced by G6. For the dataset attached,
 (setting the region to match slope), i get:

 From G7:

 {{{
 Volume report on data from slope using clumps on basin map

  Cat    Average   Data   # Cells        Centroid             Total
 Number  in clump  Total  in clump   Easting   Northing       Volume

     1      3.41    268000   78593   635195.00   220715.00      26799969.96
                                             Total Volume =    26799969.96
 }}}

 and G6

 {{{
 Volume report on data from slope using clumps on basin map

  Cat    Average   Data   # Cells        Centroid             Total
 Number  in clump  Total  in clump   Easting   Northing       Volume

     1      3.43     29854    8715   635175.00   220725.00      26868600.00
                                             Total Volume =    26868600.00
 }}}

 Thanks, madi
