Your response unfortunately does not make sense. While you correctly point out a mistype in my post, this is not relevant to the substance of my report.
If the first wave, as you state earns 68,380 points. Why is the wave modifier after the second battle 29,900 and not 68.380? Why are the total points earned for defeating both waves not 68,380+29,900 = 98,280?
You refer to the update in 1.30 but the changes mentioned in that report has nothing to do with my report.
The changes in 1.30 state "Defeating just one army wave won't give any battle points."
This means, if you defeat the first wave, and fail to defeat the second wave, you won't earn any points.
