"... set aside sufficient time ..."

[Kes13a]

They don't have to give an exact time (I.e. 25 minutes, 43 seconds). A rough estimate (I.e. Approximately 25 to 30 minutes) would work fine.

dear sir/ma'am, personal question, whats your reading level? do you want SE to put a reading quiz in before you start the game so they can determine how fast or if you can read? you cannot really "rough estimate" reading speed. and no matter what your estimate, its going to be wrong for a lot of people. then you have complaints about "it took longer than you said", or "I expected it to be longer so I left to do X..."

so, sure, if they put in a reading test, to determine your level of speed and comprehension then they could ballpark the time it takes for you personally. problem with that is, I know a lot of people wouldnt be okay with that, I mean they complain about the most minor things already...

ps. is that better Midareyukki?
