YEAR = 86400 * 365
INITIAL_RATE = 274_815_283 * 10 ** 18 // YEAR
RATE_DENOMINATOR = int(1e18)
RATE_REDUCTION_COEFFICIENT = 1189207115002721024  # 2 ** (1/4) * 1e18

rate = INITIAL_RATE
for i in range(1, 500):
    rate = rate * RATE_DENOMINATOR // RATE_REDUCTION_COEFFICIENT
    print(i, rate)
    if rate == 0:
        break

Values and calculation are copied from the actual CRV contract:

In particular we apply integer division as in the vyper code and reduce the rate by ~16% each year.

Output:
1 7327853447857530670
2 6161965695807970181
3 5181574864521283150
...
243 2
244 1
245 0

Thus we see CRV emissions will end in 245 years from the start.
