Misleading/Incorrect claim regarding compression.
The README states "They said 100% compression was impossible? You're looking at it!"
There's a fundamental flaw in this statement:
Compression % = 100 * ( 1 - ( Compressed Filesize / Uncompressed Filesize ) )
So for instance we compress 100 MB of data into a 20 MB archive, then we have a compression of:
100 * ( 1 - ( 20 / 100 ) ) = 100 * ( 1 - 0.2 ) = 100 * 0.8 = 80%
In order for us to have a 100% compression, we'd have to compress our files down to 0 bytes.
We still require massive amounts of storage to index the digits of pi and we still need storage space for the software that is supposed to calculate the digits of pi in order to retrieve our information.
So it's probably best to state that this method is almost 100% compression instead.
