I am nearing 500 now and while i add 20 sentence (no more no less) everyday, I notice my reviews are increasing every day. Now I average 50 cards a day review. It takes me on average 25 minutes a day to review those.

So is it safe to assume that I will have around 100 a day to review at 1000 total cards, 200 reviews a day at 2000 and so on? when i hit 5000 cards thats like 500 reviews a day. At my current rate it would a little more than 4 hours a day to review that many. And thats just 5000, at 10000 i would be spending 8 hours a day reviewing.

As I add more sentences, is it safe to assume I will get faster at going through the sentences?

I also am mining my first 500 or so sentences out of the grammar book suggested on AJATT. So maybe learning all the different grammar concepts at the same time is attributing to the longer review times.

Anyone with a ton of sentences already how many minutes do you need to spend reviewing a day? Thanks.

Nope, the idea of spaced repetition is that reviews are, well, spaced further and further apart - resulting in less reviews per day.
I have now around 5000 cards in my deck, and I only have around 40 cards per day. (However I did not add any cards for the past half year or so).

Anyhow in your case (adding 20 a day) reviews will get up some, when you feel overwhelmed just stop adding cards and after a month or two, reviews will go down, making your life easy

You can actually choose to do however many you want each day.

Doing 20 cards per day will never add up significantly. I add 100-200 (vocab) cards per day and even that is easily manageable to me (30-50mins of review time).

*note: I am a 完全主義者, so I add every word I encounter that I don't know into Anki. As a result I have words like 残尿、相対性理論、千木、etc.

There is not a direct relationship between total number of cards and the reviews.

If you maintain a constant number of new cards per day, at a fairly consistent pass rate, yes the overall number of cards per review will go up over time but the rate of increase should increasingly get slower and slower. This is due to the intervals on a lot of your "early" cards becoming extremely long.

Think of how the SRS works in terms of creating reviews for you. When you pass a card you send it out to fill up a "slot" in the future. When you reach that slot you'll have to review it. Well when you first start out your cards are at low intervals so you have a lot of cards being sent out into the first few weeks of "slots", with many of them overlapping. This is due to Anki's variance. It tries to spread the cards out over a given range based on a percentage. When you are at low intervals this range is quite small so naturally a lot of cards have pile up on the same days. Well once you have been reviewing for a while you'll have cards being sent out to slots far in the future where there is a ton of variance. This means the cards can be spread a lot "thinner" (aka less cards per day).

So eventually these long interval reviews will start to trickle back into your reviews but at a very low rate because there is so much variance that they are hardly ever clumped up with a bunch of other similar high interval cards.

The most important factor basically comes down to the number of new cards added per day. And wow I didn't mean to type that much lol.

Ahh I understand now. Thanks a lot everyone.

Someone did a graph that simulated adding cards with a pass rate of 90%. I think it came to about 13x your daily adding rate to where reviews begin to taper off. So if you add 20 cards daily, expect to reach roughly 260 daily reviews after 3 years.

If you use anki, it has a better spacing algorythm going from 2.0 to 2.5 for standard passing, so the reviews will be even less over time.

260 daily reviews are far too much though! ... isn't it?

considering you would have over 21k cards, no it doesn't sound too bad. Especially assuming you would be (1) quite adept at previously digested material and (2) have your study patterns down.

I have 5400 cards, add somewhere around 10 per day and review an average of 100 per day and it's not very draining at all. I think, no matter how many cards you have, there are other ways to simplify the whole process of reviewing aside from keeping the amount low. Once I felt I was familiar enough with the language, I started to only put great focus on the words/phrases in the sentences which were the reason for adding the sentence. Example: "ら行の発音もへんだった." This was added to familiarize myself with how ら,は、さ, etc and 行 are combined to mean the set of 5 "ら、り、る、れ、ろ” "は、ひ、ふ、へ、ほ” etc. Most of my time and attention will revolve around "ら行." And that won't even take much time.

In the beginning when adding sentences, I would add excrutiatingly long, nearly-run-on, stanza-like sentences to my deck which I come across every once in awhile. I keep them in their for memories/humor

Plus, here's some reality checks

You're never going to consistantly add a set amount of cards. Sometimes you'll add more, sometimes less.

The x2 (3 day, 7 day, 2 weeks, 4 weeks, 2 months, etc) spacing with 90% miss (miss going back to 3 day) created the x13 number. Reality is your miss rate will be different. Plus, Anki doesn't send missed mature cards back to zero, and it spaces cards faster which means less reviews on average.

Plus as Brianbush points out, when you have 21,000 cards of whatever, reviewing 1% of them a day doesn't sound too bad at all.

The amount of cards you can manage per day depends on what they are. If you're like Jarvik adding only vocab cards then it only takes a few seconds per card. I usually do recognition only sentences, and average 10~15s per card. jacf29 seems like he's spending 30s per card.

Indeed, my speed is 1-4 seconds per card on average I'd say.
