I'm doing RTK2, at about 200 frames now. I've been ignoring the meanings and only learning the readings of the focused kanji. Should I learn the meaning of the compound or just keep on learning the reading only? I'm also doing core10k alongside. Maybe I should drop RTK2 as a whole and just increase the amount of 10k I'm doing per day?

The vocab that RTK2 uses isn't always all that common. Trying to remember both things might slow you down.

When you say you are doing RTK2 does that mean 1 card for 1 reading for 1 kanji? I think if you're having no problem remembering readings for the core10k that youre doing, you might be better off dropping or doing abridged version of RTK2. I think you can get most of the benefit of RTK2 by just learning the phonetic compounds and their readings, rather than trying to remember every kanji that uses them.

Yeaah.. Now I think that it's not really worth doing RTK2, cause it's a pain to learn the readings only and learning the meanings along would just mean you're learning vocabulary, and that's what the 10k is for.
The optimized 10k isn't even that hard, the list is compiled so that same kanji appear next to eachother, and their readings (even some kun readings) sound the same or are atleast relatively similar. So it's no problem learning 50+ vocab a day.

I think I wouldn't necessarily say that RTK2 is worthless. The signal primitives are very helpful.
Though, I have to say, you're supposed to learn the readings *through* the vocabulary that he provides. The book is structured so that you can learn all the readings with as few new vocab as possible, to minimise the burden of having to learn two things at once. There's a fairly decent RTK2 the book deck up on anki, which I used, but it's based on the 5th edition. I am slowly slowly making progress in trying to update it to the sixth.

Good plan, I'd say. With a rate like that you'll make good progress in no time.

RTK2 can teach you some neat stuff, I guess, like how lots of stuff with 同 is pronounced　どう or how things with 青 are pronounced せい. But you usually pick up on stuff like that anyway, and it can end up being just a big distraction from practical study.

I have more or less ignored the meanings and just concentrated on the readings.

I find that doing so has helped me a LOT while making my way through core2/10k.

Today I did another 50 words in 10k, very easy. Took me about 10 mins along with the reviews I had from yesterday which were about 50, I know they're going to stack up in a few weeks, but even then I don't think it would take any more than 20-30 mins to keep up. Even though I noticed a few readings I learned from RTK2, it doesn't bother me at all that I quit RTK2, maybe it would've been a slight help in doing the 10k, but it's not worth spending months on it only to help you learn vocab which you can start learning without RTK2 and make much more progress meanwhile.
I think that I'll increase the amount of vocab a day soon, since the words seem to stick without any effort, but I still click "1 day" on most of them just to make sure.
