Hi Sherman,
I would like a different computation of the percentages:

In contrast to 'saved computation time' ...
either measured in 'performance gain':
1 13,409,610 2,990,525 (448%) 13,196,357 (102%) checksum=bd00bd
2 5,808,804 1,664,460 (349%) 7,069,931 ( 82%) checksum=19000d3
or measured in 'effective computation time':
1 13,409,610 2,990,525 ( 22%) 13,196,357 ( 98%) checksum=bd00bd
2 5,808,804 1,664,460 ( 29%) 7,069,931 (122%) checksum=19000d3
