docs: the README's All in one numbers are those of the run of hardware check 94
5309 to 5353 it/s, 185 to 166 W, fans 70 to 52 %, in 31 minutes, with v0.4.6.
The two earlier runs are named next to it; the screenshot is of the first of
them and says so.

**All in one** is the default: it overclocks, undervolts on top of that, measures the quietest fan curve and tests the whole for five minutes. One run on the reference card, both columns five minutes of full load (the picture above is of an earlier run and shows that run's numbers):
A little faster, on less power, with slower fans. The card is warmer because the fans are allowed to be: the fan tune aims for 70 °C, 5 °C under the profile's limit, and found that 52 % holds it. With the NVIDIA driver's own fan curve the same settings ran at 63 °C on 176 W. The run took 34 minutes. A second run gave 0.9 % more score on 10.8 % less power, with the fans at 55 %.

As fast or a little faster, on a tenth less power, with much slower fans. The card is warmer because the fans are allowed to be: the fan tune aims for 70 °C, 5 °C under the profile's limit, and found that 52 % holds it. Before the fan tune, with the fans on the profile's own curve, the same settings ran at 66 °C on 163 W. The run took 31 minutes. Two earlier runs gave 1.6 % more score on 8.2 % less power with the fans at 62 %, and 0.9 % more on 10.8 % less with the fans at 55 %. How much memory offset a run finds differs from run to run on this card (+550 in this one, +1500 in the first of those); the score barely moves with it.

The gains are smaller than those of the two sections below, and that is the point of it. An overclock and an undervolt do not add up: an overclock moves the whole voltage/frequency curve, so at every clock the card already runs on less voltage, and with the same safety margin there is nothing left to take off. They are two ends of one line. All in one takes the middle, where the card beats stock on both counts; **Best of my GPU** and **Undervolt** are the ends.

In an earlier run an emulator on 11 % of the card cost 6 % of the score; the run now says so when its final test does not match the step before it. The logs are in [docs/hardware-checks.md](docs/hardware-checks.md) (checks 75and 76).
