What is the max number of lessons you managed to reinforce in a single day?
I'm new to the forums, so sorry if I got anything wrong here.
On a really boring shift, a long train journey or sick in bed, I have managed as many as 70 on a single day. Generally, however, my average is more 15-20.
Btw, it's usually nicer if your title is an actual title and you take a little more time to explain your question in the actual text of your post. You could, for example, include the reason why you're asking or elaborate whether you ask for realistic numbers or the absolute extreme people have ever managed.
