how global-avg-total-response-time is calculated?

[#1]

I have this response of stat with avg(total_response_time) select,

"data" : [ {

"identifier" :

{ "names" : [ "apiproxy" ],

"values" : [ "xx" ] },

"metric" : [ { "env" : "vvv",

"name" : "global-avg-total_response_time",

"values" : [ 2.32183908045977 ] },

{ "env" : "vv", "name" :

"avg(total_response_time)",

"values" : [ 4.0, 3.0, 4.0, 0.0, 0.0, 0.0, 0.0, 2.197969543147208, 2.5048076923076925, 5.0, 3.0 ] } ] }, {

i tried to calculate it by

Sum(4.0, 3.0, 4.0, 0.0, 0.0, 0.0, 0.0, 2.197969543147208, 2.5048076923076925, 5.0, 3.0)/7

but the result wasn't 2.32183908045977
