As we all know, Heisig is all about order.
His order is optimized for learning rather than effeciency in gaining literacy. When learning kanji by frequency, more words can be spelled with a fixed repertoire of characters. I was interested in how grave this difference actually is, and did some plotting:
I took JMDict, which is quite comprehensive and contains about 130000 entries - most of them being kanji words. I then checked how many frames a student must have learned to spell the entire word.
This is matched against the "common" order of learning Kanji. For this i used the frequency index found in KANJIDIC - which is far from accurate, but should suffice the job:

Nothing surprising there. The Heisig graph is exponential, which is to be expected when using any random order.
The frequency is somewhat logarithmic. This is also obvious, as the additional kanji become less useful.
Another statistic arising from this is the number of *new words per frame*. It's the number of new words you can spell when learning an index/frame (given you only know kanji of previous frames). For frequency order it obviously goes downhill (which is the whole meaning of it). Heisig is more evenly distributed, and even increases towards the end.

And this is my motivation to all of you learning RTK! Imagine learning in frequency order: You're at your 2000th-and-something kanji, learning it only to be able to spell a handful minor words. I'd not be very motivated to continue.
Heisig however keeps rewarding you for your studies, even later frames are as useful as any other.
The "best" frame in this context is actually 1885 (気) as it adds over 1000 new words!
So for learning ALL kanji, it might not be the best choice to chose that speedy path
And at the end of the day, common characters aren't necessarily useful ones.
