I have just finished my testing.
Yesterday it was raining and I had no school so I decided to go out and try my maccat micro. There was supped to be 3inches of rain and wind up to 40mph

When I got out it was pouring rain, I set up the tarp as low to ground as I could. I set up my hammock. I was very happy with the continues ridge line I put on it. It helped allot for making sure the tarp was over the hammock

I then watched ‘batman begins’ on my iPod.
Over two hours later there was not a drop of water on me or my hammock. The forecast called for 40mph I don’t think it got any were near that that kind of wind speed.

I have concluded that the maccat micro is a sufficient tarp for 3 seasons in Irish weather. But if there was going to be a lot of wind driven rain then I would go with a tarp with more coverage. I took a video of the inside of my tarp after I had watched the movie. My only regret was that I could not spend the night in my hammock as I had school the next day.
