To be honest i really think it is simple and easy .
All we have is 400,000 MARI daily and that is a fixed number never change (increasing or decreasing) . Those 400,000 MARI is divided by the number of total claims by the end of the day .
And that determines how much every claim worth of MARI at the end of the day.
so your shares from the 400,000 is simply . Number of your claims at the end of the day * ( 400,000/total claims at the end of the day ) = the amount of MARI u get at the end of the day
no one have said it is complicated to get. the fact is that the site shows an amount of mrai earned that is variable, if you stop claiming by midday the amount you saw when you left the site will never correspond with amount calculated by the end of the day, at least that everyone in the world stop claiming at the same time.
Hugly unlikely, dont you think?
