Long ago I calculated 1 Ghz-days to be ~ 171 TeraFLOP (Not FLOPS)

Now we can calculate it more easily from here:
https://www.mersenne.org/primenet/

Under "Aggregate Computing Power" - "Today, last 24 hours" we can see that:

123137 Ghz-Days = 246.275 TFLOP/sec * 86400 sec = 21278160 TFLOP =>
1 Ghz-Days = 21278160 TFLOP / 123137 = 172.8 TFLOP

We can test "last 7 days" and "last 30 days" to see if we get the same results:

994150 Ghz-Days = 284.043 TFLOP/s * 86400s/day * 7 days =>
1 Ghz-Days = 172.8 TFLOP


4395208 Ghz-Days = 293.014 TFLOP/s * 86400s/day * 30 days =>
1 Ghz-Days = 172.8 TFLOP
