The Hunter's Journal doesn't count for 112%, but it has its own achievement. Here it is entry by entry, from "not encountered" to "completed", with the kills you have left to decipher each one, just as the game counts them.
The game's total isn't 164: it starts at the 146 the Hunter's Mark requires and goes up with each optional entry you find. Import your save and the Journal fills itself in.
146 completed. The other 18 are optional.
With the first kill, not on seeing the enemy.
