Time Spent Watching for rewatches is miscalculated.

While Rewatching an anime, the Time Spent Watching ends up being calculated:
 ((CurrentEpisodeInRewatch + TotalEpisodes) * CompletedWatchthroughs) * AverageDuration

So if the anime is 200 episodes and you are on your 4th watch through on episode 100, its calculated as
300epi * 3watches * 25min
900 * 25min
375 hours

When it should be:
 (CurrentEpisodeInRewatch + (TotalEpisodes * CompletedWatchthroughs)) * AverageDuration

(100epi + (200epi * 3watches)) * 25min
700 * 25min
291 hours, 40 minutes

Also, after the rewatch is over, the Time Spent Watching goes back to ignoring rewatches entirely:
 TotalEpisodes * AverageDuration

Actually the problem is not just that.The problem is that MAL is not counting correctly the rewatched animes value.

I figured that out because of this comment here (Then read my reply on the next comment)

You can also manually check that on his profile, like I did.This is a really weird bug that I would like to understand why its happening.I probably should have reported this too.

They need to fix both the rewatched values and also the timming for them, maybe the timming is working, but because the rewatched values are not correct the timming is also wrong.

I didn't find this to be true. So long as the last episode is incremented using the + button and the prompt that comes up that says "Do you want to set this show as finished rewatching?" and you hit "Yes", it increments the Rewatch value on the per series value (when you hit "More" on a series next to the edit button), the one on the profile is wrong, but that isn't what's used to calculate time spent watching.

Sorry, that's just not the same bug I'm having. My profile "Rewatch" value is wrong (only says 6, should be several more), but my per series one is correct. But how that value is used to calculate the Time Spent Watching is wrong and is calculated how I said above.
