So basically it could be that if the pressure is higher than what it ought to be, it is likely to be not visible once the gas has ionized, but it may still affect the ionization time?
The strangest thing what happens is that if I leave this tube off for a while (say 15 minutes) the ionization process is usually slow. On the other hand, if I trigger a time reading just a few times after each other, the first reading might be slow but all the next readings will be just normal.
