At what point does a sin Truly count for a Revert, like is there a certain degree of Knowledge he learns then when he learns it whatever else he has learned beyond that is counted for him, or if he contines to do lots of sins like Zina and the major sins they don't count to a certain point?

Ustadh AbdulAziz al-Haqqan

They count if he knows it is forbidden, and he must learn the deen.
