Sample size = 1000 refined Dex crystal -> first appraisal // 100,000,000 mesos
740 low grade + 250 mid grade + 10 high grade
First pass low->mid // 22,000,000 mesos
266 low grade + 44 mid grade
Second pass low->mid // 7,800,000 mesos
93 low grade + 15 mid grade
third pass low->mid // 2,700,000 mesos
30 low grade + 5 mid grade
10 + 2
New total:
316 mid + 10 high grade
First pass mid->high // 15,500,000 mesos
199 mid + 9 high grade
Second pass mid->high // 10,000,000 mesos
125 mid + 6 high grade
80 + 4 // 6,000,000 mesos
50 + 3... // 4,000,000 mesos
End result: 1000 dex crystals + 175,000,000 mesos = 35 high grade. Average cost: 28 crystals + 5000000 mesos.

And by extension (for the poor people)

1000 dex crystals + 132,500,000 mesos = 316 mid + 10 high grade = 316 mid + 10 * (28 crystals + 5000000 mesos)
1000 dex crystals + 82,500,000 mesos - 280 crystals' worth of mesos = 316 mid grade.
Average cost of mid: 2.3 crystals + 260,000 mesos (or more accurately, 3 crystals + 260,000 mesos - 0.7 * price of 1 crystal).

Warning: Silly calculation follows.
1000 dex crystals + 100,000,000 mesos = 740 low + 250 mid + 10 high
720 dex crystals + 50,000,000 mesos = 740 low + 250 * (2.3 crystals + 260,000 mesos)
250 dex crystals - 15,000,000 mesos = 740 low grade.
Average cost of low: 0.33 crystals - 200,000 mesos.
In reality the only reason you'd need mass low grade crystals would be to convert them, and if you actually intended to use them you might as well just appraise -> keep a few low grades instead of converting.
