Example of how to use the pledge calculators for pool operators to get a rough idea. Not financial advice 🙂

Hi Rick,

Yesterday, I created a very simple func in [desmos](https://www.desmos.com/calculator/rscf3lb4jn), in which gives you the pools’ epoch reward, and you just need to fill in the following parameters:

- S = the total delegated stakes 12.8bn for ITN,
- p = your pool’s pledge,
- d = pool’s delegated stakes (p is excluded)
- R = Epoch’s reward for ITN. it is the genesis’ parameter the `reward_parameters` ITN genesis constant  
in ADA i.e. 3835616.44
- k = pool numbers and, default 1000
- a0 = the security parameter, default=0.1, 10%, but it does not apply to ITN.

Thank you Pal, I will get some practice using this and make a demo video. This will be good practice running some test variable and compare them on the Haskell test net.
