https://docs.google.com/spreadsheets/d/1BhKbWPaMhPhSG9XyIa3hcJO5OvR1h05zbQ7vdxoe17k/edit?usp=sharing I made that sheet for scoring during the event (its essentially the old one with storms added) Sheet 1: Points earned as PH10 vs PH10/9/8 at each PR bracket, with and without storms and or rival bonuses, at 3/2/1* Sheet 2: Total attacks needed to get the final reward, at each of these levels. Sheet 3: Clone it and put in your average gem cost for your army, and it tells you total gems needed to complete the event in one streak without waiting out any of the rehire time.
Just a quick followup - sheet 3 does not factor in streak reduction, so its a maximum cost - in reality, you will be spending less as streaks reduce gem cost. It is currently estimating it based on a 15-gem army, which you can easily change to your own army cost. But this gives a good high-ceiling on total cost, and overestimating it gives you a bit of buffer for the couple attacks you may screw up.
