Dash.
I have no doubt there is some variation ... No measurement is 100%.
Even within the dash +/- range ... I still do not think the Gen-1 Insight has to be going "pretty slow" in order to achieve average of ~70 MPG ... because I can and do that or better within +/- 5 MPH of the posted speed limit ... which I think +/- 5 MPH from the posted speed limit is not considered "pretty slow".

In short ... I don't think any form of measurement is 100% ... they all have their +/- minus range ... be it the dash or the pump.
There are issues ... often ignored ... with using pump given gallon numbers ... the pump is not 100% accurate either ... no matter how many digits they show you ... that is not the number of digits of accuracy that pump is obligated or celebrated to ... legally many states let them pass and get a department of weights and measures sticker as long as they are within +/- 2% ... ie it reads 10 gallons but you might have actually got 10.2 gallons or 9.8 gallons ... and they would pass just fine ... which I think +/- 2% is fair ... and what happens to the pump that is 10% off ... when it gets tested again it gets a fine ... that's it ... how big of a fine does it have to be compared to the 10% or so more profits they got from a miss counting pump ... no notices ever go out ... no refunds ... etc.
So unless you are using a higher than 2% precision measuring device / system ... that ~2% +/- is all the precision I would give the average gas pump to be good for ... also even if the pump was 100% perfect ( and it never is ) gasoline evaporates , changes density with temperature / pressure , etc ... what I pump in today , might not actually be the number of gallons in it tomorrow ... nor used while driving ... even if it has not been driven at all , and none has been used from one day to the next.

As for fuel log ... It is not about bragging rights for me ... I have no intention of participating in that ... not my thing ... YMMV ... if you want to discuss the pros and cons ... how things work ... that's fine with me ... but if it's just about mines bigger than yours ... I'm not interested ... And I would be just as not interested even if I had 10x the MPG ... I don't care for that... which is why I am loathe to even post my current numbers ... it's a slippery slope into a mines bigger than yours type thing I have negative interest in.
But ... I'll cross my fingers and hope your request doesn't turn into that
Although I am loathe to go down this slippery slope....
My Dash Current tank is 78.7MPG for 372.3 Miles ... driving my commute and such within +/- 5 MPH from the posted speed limit.
Running average of this tank and the two previous tanks ( including times when my wife drove ) 76.3 MPG for 1,428.5 Miles
And mines not magic ... there are others who also get ~70 or so MPG on their commutes without going 'pretty slow'.
Context / details matter Allot ... YMMV ... I've known people who averaged as low as 19 MPG in their Gen-1 Insights ... and others up around 90 MPG ... it varies with a wide variety of details ... some of it is driving slower ... but not all of it is just driving a slow average speed.
