 ![A Blue-Ray disc and a Floppy disc.](./floppy.webp)
 I roughly estimate that the fix saved some big cloud providers the equivalent storage size of one Blue-Ray disc, and most companies the equivalent storage size of one Floppy disc.
 
-The bug occurs when Prometheus stores n bits where n is a multiple of 8 and when the previously stored bits count is also a multiple of 8. If we have a uniform distribution, it's 1/8 * 1/8 = 1/64 of the time. We can say it's a byte saved in about 1% of the Prometheus data chunks. It matches my observations.
+The bug occurs when both the bit size of the last encoded value to be stored and the number of already stored bits are multiples of 8.

 Prometheus has many data chunks, as a chunk usually contains [only 120 samples](https://github.com/prometheus/prometheus/blob/faf5ba29bade4d2483b491013363fddfbc301def/storage/series.go#L285). How many chunks are stored per Prometheus instance on average, and how many Prometheus instances are running worldwide? I don't know.
