Should I ever see nitrites during my 3 day test?

[LittleDragon]

Hello everyone,
I started a 3 day test for my cycling tank and out of curiosity I checked levels 12 hours after dosing ammonia just to see how things were progressing. My ammonia was down from 4ppm to about 0.25ppm, but my nitrites were at about 1ppm; does this mean my tank is not cycled even if nitrites process to zero by the 24 hour mark?

if the nitrites are zero after 24hrs then it is cycled,
