Methodism starts only in about 1784. That’s totally about 230 years, not 300 to today. And i,pf you count until the 60s then it was less than 180 years old. In any case it hardly made any inroads to India - that’s why less than 0.5% of Indians are Anglicans/Methodists/Lutherans/Calvinists.
You are correct about the start date of Methodism. My bad. (I knew there was a reason I liked art so much more than math.)
