15:59 < ocharles> klrr_: that's euler integration
15:59 < ocharles> klrr_: the idea is that we assume the thing being integrated is a stepped graph
15:59 < ocharles> so we take the last produced value and multiple it by dt - which means we assume 
                  that for dt seconds the value was the previous value
16:00 < ocharles> then we add that onto an accumulator
16:00 < ocharles> so we're approximing an integral by sampling at some frequency and assuming a 
                  'rectangle' under the curve until the next instant
