Interesting. In the US you can donate plasma twice a calendar week as long 48 hours separates the donations. I use to do red blood and double red as frequently as a I could, the day I became eligible again was the day I donated. When you do something like that you can't worry if you are donating enough - you know that you are doing everything you are allowed to do.
