Activity Score calculation

I’m curious is to how the Activity Score is calculated. Could anyone show me the equation used in the Activity Score? thanks

Activity score includes all of these: LingQs created, LingQs learned, speaking events (15-minute conversations attended), words of writing (through submissions on Exchange), minutes of conversation hosting and days logged in last month. 10 points each day you access a language, so 300 activity points over 30 days if you actively study a single language every day through the site.
