How much sleep in the log

Lashawn
Hi, there some days this week, including in the last previous few weeks and one of the days I first downloaded this <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> that I guessed the times of when I went to sleep. I wasn't paying full attention to the times on some of the days in this week and the last previous few weeks that I went to sleep, so, I just guessed the times even though they weren't the right times. Is that still okay? Thanks.
