We have a curation reward of around %9 percent. My actual curation reward APR is %9,24. When we sum the figures %3+%9, we find a net positive return.

I calculate SPS inflation using https://next.splinterlands.com/dashboard/sps data. I consider the change in total supply. So, I suppose it is correct. SPS staking return is around %23 percent, and we have a %7 GLX airdrop return.
