Total Throughput calculation on html report is not correct

**Ashok Reddy** ([Bug 64846](https://bz.apache.org/bugzilla//show_bug.cgi?id=64846&redirect=false)):
sum of all sample request throughput is not matching with total throughput:

Example:-
sample 1 throughput - 9528.37
sample 2 throughput - 2219.28
sample 3 throughput - 1900.87
sample 4 throughput - 3443.52

---------------------------------
Sum of all samples - 9528.37+2219.28+1900.87+3443.52 = 17092.04 but in HTML report total throughput is showing as 7603.34

can you plz help how this calculation happens

output summary:-
summary = 10500000 in 00:23:01 = 7601.6/s Avg: 54 Min: 3 Max: 2479 Err: 441 (0.00%)
