This is a little hard to believe.  If you've been doing Core6k for 3 years and you're only at 4000 cards or so, it doesn't make any sense why you'd have 100 reviews a day, unless you fail cardes a lot and have a lot of young cards.  If you're getting 90% correct, then you shouldn't be failing a lot, and you have should a lot of mature cards.

Unless you've done something weird like adding a bunch of cards recently, taken long breaks and let a bunch of cards build up, or something like that, it doesn't make sense why you have so many reviews.  Do you have any idea why you have so reviews everyday?

As a reference, I finished Core6k two or three months ago, and I'm slowly chipping away at Core10k.  It took me about a year and a half to go through Core6k.  Right now, I only have about 60-80 reviews a day. 

I remember someone else talking about Core6k.  He finished Core6k and continued reviewing for a year or two.  At that time he only had about 10 reviews a day. 

So you can see why you're 100-150 reviews a day is slightly unusual.

(Also, this is less important, but I would also say you're taking too long on each card.  If you take more than 10 seconds on a card, I would recommend immediately failing it and going on to the next card.  Using this 10-second method, I can easily get through 80 cards in 10 minutes.  If I'm really rushing, I could probably get through 100-120 in 10 minutes.  My fail percentage goes up slightly, but not too much.  90% is pretty high, so I wouldn't worry if it started to fall a little bit.)

As for the reported number of the OP on their cards it could be due to a (very, very) long break after getting to something around 2k and then a recent big push on the other 2.5k to get to 4.5k. That would explain the time and the high review numbers.

There's nothing stopping the OP from keeping the core 6k deck going at a slow pace (maybe 10 a day) after bringing the review numbers down and at the same time going one with reading native material.

You're right.  That's why I was wondering about the percentage of young cards in the deck. 

If OP basically stops adding new cards, and just starts doing reviews, the number of reviews per day should drop dramatically in a month or two.  This should make it more manageable.  After that, only adding 5 or 10 cards a day would still give progress (hell, only 5 cards a day would let him finish Core6k in less than a year), but it should result in less reviews than he is currently doing.

I guess we have to wait for OP to get back with the reason his numbers are weird.
