I agree with you. The statelessness of the HTTP protocol gives rise to such issues like the ones I'm bringing out right now.

The pages that the users are viewing are practice exams from subjects being offered by a training center. The length they stare on a page is dependent on how fast they can solve the problem. Logging-out is mandatory. However in some unforeseen circumstances like a power failure, I wouldn't want to charge-up those "minutes".

I had once an "unlimited access" scheme, but the problem this brings is that user simply shares his account with another. To addresss this, we agreed to have limited access time for users.

I believe giving the user a 5 min to 10 min penalty for not logging-off properly is still fair. I wouldn't bother if they stay on the same page for two hours since all they can do is to stare on a single page with a single question... and nothing more. To get additional information, they need to navigate to another page.
