Even though I finished writing the groups that Heisig originally created into sheets, I still have a lot more to do.
Out of a total 3000 Kanji, Heisig did not put around 1553 Kanji into any sound groups.
Although he didn’t group many Kanji into specific groups, a lot of them could be easily grouped together with groups he already made.
Not only that, but he has duplicate groups which are redundant.
So it really made me wonder, why didn’t Heisig just clean things up a bit and try to group more Kanji together?
But as I’ve been working on this project, I’m starting to realize why he left a lot of Kanji ungrouped – this is a lot of work and it requires a lot of editing, which means a lot of time.
