1) regular-latency.pngI'm wondering whether it would be clearer if the percentiles where relative to the largest sample, not to itself, so that the figures from the largest one would still be between 0 and 1, but the other (unpatched) one would go between 0 and 0.85, that is would be cut short proportionnaly to the actual performance.I'm not sure what you mean by 'relative to largest sample'?

`You took 5% of the tx on two 12 hours runs, totaling say 85M tx on one`

`and 100M tx on the other, so you get 4.25M tx from the first and 5M from`

`the second.`

`I'm saying that the percentile should be computed on the largest one (5M),`

`so that you get a curve like the following, with both curve having the`

`same transaction density on the y axis, so the second one does not go up`

`to the top, reflecting that in this case less transactions where`

`processed.`
