Thank you @stakey!
That’s a cool (well, to my taste) part.
1.6128 is correct estimation of rewards for performing validation duties (Node Operator rewards)
But the bond provided is aslo staked, therefore generates: 32.4 x 0.035 x 0.9 (applying 10% stETH fee) = 1.0206 ETH/year rewards
Total rewards are 1.6128 + 1.0206 = 2.35125 (+135% over 1.12 ETH / year).
Or +132% over 1.134 if, to compare with the same capital, we suppose that 0.4 ETH remaining from one solo validator in base scaneario is also somehow staked with 0% fee )
