Yep at the end of phase 2.

I think the best way is to measure it - reference

I have not done it myself, but with dirty math here it is.

```
Assume linear increase of space in phase 2 (which is oversimplified),
Start 160GB --> End Z GB? ; Z is the max size possible of the "on-going" plot size
floor(min(phase 2)) = 4472
space = 160 + (Z-160)*T/4472 ; where T is phase 2 time elapsed
The most critical is when 8 plotters reach the apex at the end of phase 2.
The slowest plotter has not reach its apex so it uses slightly less space. The critical point is:
max(phase2) - min(phase2) = 95.96 s = (Z-160)*95.96/4472 GB max differences
Find the real space at the end of phase 2:
8*Z + (Z-160)*95.96/4472 = 2000
Z = 249.8 GB which is less than 250GB ; dirty conclusion
```

To do the proper experiment, I would:

- Run the single plotting 10 times and compare the disk used in the same graph > to see if there’s variance. we know that final K32 final plot size has variant size, but I’m not sure about the “on-going plot size”
- Run the 8x plotting 10 times and and compare the disk used in the same graph
- Or just study the code, which I do not have enough skill
- Focus on that
**10GB** up and down variance at the end of phase 2!
- Log the data in smallest time increment

BTW Your CPU is so powerful.
