Notes

The model that loads is of revival growth taking placed in a population that is growing through migration. All the migrants are unbelievers. There is an initial burst of rapid growth followed by repeated bursts of revival growth due to the pool of susceptible unbelievers continuing to increase and tipping the church over the revival growth threshold.

Change the number of immigrant enthusiasts to 25 per year and there are no repeated bursts of revival growth just the initial one, followed by steady growth and an endemic state of enthusiasts. See the migration results page for details.
