What slope? I always install the terrace without a slope, the rain flows through the joints – a slope is only really relevant for the substrate so that the water can drain away.
A wooden terrace has the advantage that it can be level.

P.S. The little bags can be modeled like putty, however you need them.

No, once the terrace is on it, nothing moves anymore (actually, if it was done properly and cleanly).
It also makes no sense for another reason. The bags are not heavy, meaning the bags "hang" on the beam and not vice versa.

Sorry, but you have to explain that to me now! Water cannot remain standing on any wooden terrace in any significant amount. That is physically impossible and proven in practice as well. Or have YOU ever seen a puddle a centimeter high on a plank? The water simply evaporates through the joints and then has to drain below the terrace. It does not look any different on a rainy day than a stone terrace (with a slope). It doesn’t have to be. It’s enough if the rain can drain off. That is easily possible with joints of about +/- 5 mm. Snow and ice are not liquid water. Snow even remains on my house roof despite a steep slope. A terrace, whether wooden or stone, will also freeze over. Hoarfrost will also form there. All of this has nothing to do with slope.

One does it, among other reasons, because of the forming biofilm, but also to get sinking water off ice/snow more quickly.

It's not for nothing that every provider of deck boards specifies this or recognizes it as a defect if the landscaping gardener does it without.

Which does not mean that it doesn't work - but don't tell me now that it is not necessary.

But that is exactly the case. You do NOT need it.
Forming biofilm. What nonsense!!! The same applies to thawing water.

It may say so somewhere. But that does not change the fact that it is absolute nonsense, and therefore I say again: You do not need a slope for a wooden terrace. That does not make a single drop of water drain better or keep the surface free of "biofilm". Where we come from, we simply call it green algae . That has to do with the orientation of the terrace.

Also, the grooved decking board is constantly advertised as being more slip-resistant. That is nonsense as well.
Grooved boards are a) harder to clean/maintain b) water does not drain as easily c) they rot faster d) lower risk of splinters (with wood)

Ok, then everyone else is just wrong, the standards are incorrect, and the banker knows better.

You, I only wrote what the technical rules state – I wouldn’t dismiss it as nonsense right away... you can point out that you do it differently and that from experience it’s not necessary, but there are enough laypeople reading here, so I would at least allow what the technical rules say.

And don’t write "nonsense" & "bullshit" multiple times...

But interesting that water runs off just as well/badly with slope as without – even physics is being explained anew here.

Wait, manufacturers don’t recommend a slope for nothing. It’s not about having puddles a few centimeters high, but about preventing a water film from forming. This can be avoided more easily with a slope. As for me, I would never build a wooden terrace without a slope. Especially with grooved decking boards, I would even make sure to consider a slope in both directions. My experience shows that boards on which a water film remains suffer damage much faster.
