Casper The Finality Gadget Paper : Update Checkpoints Frequency

[PhABC]

According to the latest Casper FFG paper ;

The genesis block is a checkpoint, and every block whose height in the block tree (or block number) is an exact multiple of 100 is also a checkpoint.

However, some discussions seem to indicate that this number is not set in stone (1). I would suggest updating this section to a more up to date value or simply remove the specific value as this is more of an implementation detail.
