Well, the numbers you posted show a clear distinction between when the ban went into effect and both prior and afterwards. Would reimplementing the ban stop mass shootings? No, and no one has claimed it would. Would it reduce the numbers, it appears it would. But one thing is for damn sure, survivability improves when an assault weapon IS NOT used. Look up the word. "cavitation", because survivability is the main purpose of an assault weapon ban. Would you rather your children or grandchildren be shot by a Glock or an AR-15?
