The formula goes like this:

$11 split into 75% | 25% (Author, Curator)
= $ 8.25
$8.25 split into 50% | 50% (SBD, SP)
= $4.125

Then SBD to USD (Using 1:11 SBD to USD)
$4.125 * 11 = USD 45.375

Then USD to RM (Using 1:4 USD to RM)
USD 45.375 * 4
= RM 181.5

That's a pretty detailed explanation @superoo7! Way to go!

Thanks. That's good to know.
