why some measurements are longer than others?

Hi,
I noticed that one of the first measurements takes significantly longer than the others.

Example:

import VL53L1X
import time

tof = VL53L1X.VL53L1X(i2c_bus=1, i2c_address=0x29)
tof.open()
tof.set_timing(66000, 70)
tof.start_ranging(1)

for i in range(0, 5):
    start_time = time.time()
    distance = round(tof.get_distance()/10)
    print(f"{i} measurement time: {time.time() - start_time)}")

tof.stop_ranging()

I tried to manipulate timing budget values, but no result. It's always the same.
Do you have any idea why this is happening?

Start by reproducing the reported Python example with VL53L1X.VL53L1X.get_distance(), using the shown timing budget and five-measurement loop. Trace the first-call path and compare it with later calls; done means identifying why the first measurement takes longer and recording or addressing the cause.
