I keep apprentice items below 100 (might go above that if I know I have a lot of spare time the next days) and just read through the mnemonics once and go for the review. About 2 minutes to go through 5 new items. I do leech training about once a month where I use more time to study what I often get wrong, and will write them down if I confuse the kanji with similar kanji, and look at sentence examples if I get the use wrong.
I also have New and Improved Wallpaper Generator as a background on my home and work computer with different fonts. This makes me highly motivated, and it makes me see the Kanji I have learned every day.
