Yes, and why random data? Possibly he needed 'real' data because the store used compression/RLE.

But certainly they should have got an estimate first - given a probability and size.

He was not using real data because we anticipated that with this new feature, the usage would change. (Making our existing data meaningless).

And there was no compression or anything fancy.
