Well, I think the experience plays a role. I have been doing this for 30 years now and I do many things intuitively without much thought. In the course of many years I also had to pay a lot of apprenticeship and made many mistakes and also lost many Paros. I could not really say today that Paros are difficult. Reasonable water, does not necessarily have to be very sour, and good food then it works, oh and of course patience, be patient.
if you do not spawn this year then you will be doing it next year, sometimes you just need a little bit longer 🙂
