Stupid to be out? Roll dice for results? Oh come on, it wasn't
that bad. Yes it was windy, but that truly separated those who can play in a wind. There's no random there, it's skill and experience in playing in windy conditions, which was apparent from the local guys' scores which weren't that much worse than previous day's scores. Some people are just fair weather players, never going out when it's even slightly breezy, and then they get whiny when it's windy on a tournament day. Meri-Toppila is often a very windy place to play, and I find it part of the course experience. When it was dead calm on Saturday I was even worried if all the people that came here don't get to see the true Meri-Toppila, but then Sunday delivered.
In the "Tuulinen päivä Meri-Toppilassa"-video that wind actually
fell trees on the course. That day it wasn't really smart to play, because it was dangerous.
And to the question in the topic, if you want to learn how to putt in the wind, go out when it's windy and practice putts. It might be frustrating at first, but next time you're playing a tournament in windy conditions it will pay off. Or move to live in a windy place so you
have to putt in the wind more often than not
Living here in Oulu I have seen worse winds (and played in them) many many times.
