Xiao Bai asks about the bnsol staking issue #sol #BNSOL

Seeking guidance from experts

1 bnsol redemption 1.04100618 (requires 4 days, Image 1)

However, using sol to buy 1 bnsol including fees is 1.03975, Image 2

Is it equivalent to the cost of 1 bnsol earning 0.00125 over 4 days?

Annual interest rate of 10%?
