Does anyone know how many points it usually takes to fully complete an event?

Trying to do the math to see how many levels of the event I can complete with my gems (Currently have 371), but I haven't been looking at how many points it took in previous events
My math is sitting close to 100~ points every 45 gems, assuming I buy mostly luxury bags + speed ups. Thinking of focusing more on luxury bags starting now and only using the speed boosts if absolutely neccesary
