Again, it is wrong to calculate rate of return without factoring in timing of withdrawals. From your perspective, for the example I gave (making 100K each year and pulling all out with 100K), after ten years your rate would be 27%, after 20 years, it comes down to 17%. No, it is 100% per year all the way.
Yes one is the compounding rate, which falls over time if your profits stay constant.
The other is the simple rate, which stays constant if your profits stay constant.
Still keep up the good work, neke, you are averaging 75K a year, which is very good. But i think you could do even better if you calmed things down a bit.
