For the sake of getting this off my mind I decided to go ahead and say it; as simple as I can to avoid a technical conundrum...
As a network admin, one would surely be well aware results shown locally will not always match gateway results. We know packets are differentiated between one another on various levels throughout the route, once said packets reach any 'destination' (which there are many in it's travels) header bits may or may not be included / stripped, reordered ect.
Therefore the possibility of catching an exact real time congruent match on throughput is very thin. As well as variations between calculations performed (after the fact) locally. (machine dependent latency / local filtering due to firewalls, routers, OS specific settings and load across a plethora of levels not to even mention QOS on more levels imaginable)
Stopping eons short of any technicals here, when we alter the very data we seek to explore in any way, or it's resulting computed findings, on any level, this defeats the very reason we initiated the test to begin with, since altered data within the flow is exactly what we were looking for to start with. And should be considered null and void.
Therefore we look for "real world" results. What is actually happening. The entire process as a whole while surfing, uploading or downloading, streaming, basically every day usage, never distorts , never alters or flaunts, it just is.
If i look at myself in the mirror, and choose to not see the grey hairs on my chin in the morning, and try to convince myself they are still their original color, I would call that mental masturbation , not reality.
