So for 75 SP user received 0.088 SBD.
400 / 75 = 5.33
0.088 * 5.33 = 0.469

So for 400 SP delegated you would receive today 0.469 SBD. After 7 days of delegation / investment you will also start to receive daily STEEM curation reward payouts :)

Today I've added new feature: you can receive custom delegation link like this: @tipu I want to delegate 400 sp
