when looking at this analysis done a few years ago, some have presumed that all the tall slopes are satoshi..
or that satoshi was all the blue dots and only hal was the red dot.
but its not.
initial versions of bitcoin started at a base nonce('extranonce' if your going to be an anal knickpick) of 0 and incremented up..
even when solving a block they would continue increment the nonce until they restarted the client/computer. where the nonce began at 0 again.
some versions did eventually play around with the code and set it to reset after each block had been solved.
and some set it to reset after a certain number.
thats why you see that there is a difference between a bunch of people who's nonce never really goes above 250 some didnt go above 500.. and some went all the way up, and some were random
so most will say that satoshi must be all the long lines..
but then we get into the analysis of the angle of the slope.
where the angle reveals a different hash speed (cpu speed) so a slope at nearly 10degrees is a totally different and faster cpu compared to the one near 45 degree's
over the last few years many people have looked at angles, nonce resets and other factors and worked out in the first couple weeks of bitcoin (height 0-1000) there was 9 people or possibly 9 different systems mining bitcoin not just satoshi and not just satoshi and hal.. and even more miners by the time the blockheight got to 10,000
your free to use bitcointalks search to find the analysis.
