The Max vip Level is Just for visual and the daily vip Gift, no more.. Just tested it
U get abnormal data when u try to clear too high stages, like u got 5k gs and you need 8k gs for it
If you encounter abnormal data it means you need to raise your power in game. If your power is lower than 100% in stages it result abnormal data. For example you challenge stage require 20k power and your power is 10k it will result abnormal data you need atleast 10.1k or higher the half power requirements so you wont result abnormal data.
