As purposed the *1% per week still equals to an overall cost of 1% on total tokens cashed out. Some are calculating 1 x 4 because of the four week unstake but imo that isn't the correct calculation. Wouldn't there be a one and done cashout (unless used multiple times) making the 1%/1.25 % fee a straight fee and not a compound fee.
Ex. If I cash out 100 SPS / 25 a week using the current system and get charged 1% for doing so that is 1% on 25 and the same 1% fee on the next three 25 weekly cashouts. That still equals to 1 SPS or 1% of the total casheout amount. . A minimum of a straight 5% fee would be much more reasonable.
