ᐅ Decking made of Bankirai wood: what spacing should be left between the boards?

Hello,
we have classic ribbed Bangkirai wood on the exterior and want to replace it with the smooth version. At the hardware store, the discussion came up about the spacing between the individual boards. We would like to set them closer together. The specialist said that in the past, 3 cm (1.2 inches) spacing was used, but now 7 cm (2.8 inches) is common. These spacers are only available in 7 cm (2.8 inches) anymore.
What spacing do you use? We had the wider spacing before, and it really bothered us.

Of course, it is possible to do less, but it is not advisable.
When wet, water cannot drain properly, and dirt gets trapped between the joints.
If the substructure is not adequately ventilated, the deck will eventually start to rot from underneath.
This significantly shortens its lifespan.
Unfortunately, the joint gaps alone are not sufficient for ventilation. Additional ventilation should be provided, for example, along the sides.

Since WPC still contains a relatively high wood content, it is not weather-resistant and will eventually rot. The WPC substructure would need to be ventilated in the same way. Additionally, it expands more than hardwood. It would have to be a WPC composite with properties similar to those of the hardwood decking boards. Personally, I have ruled out WPC for the substructure. It will be either aluminum or hardwood with properties similar to the decking boards.
