Did you just increase your speed recently? Or maybe you are playing more aggressively than you used too? Another possibility is you might have had some temp item that expired and gave you ~20 extra stamina?
Extension after Extension, Should just dedicate an entire day to these major updates and when you're ready to roll it out you roll it out and tell everyone about it.
I say this so you can save everyone the trouble and just work on your update and tell us when it's complete. Rather not sit here patiently waiting for the game to come online only to see yet another extension in my midst.
Don't stress yourselves and continue going until it's completed.
