Nelo models getting confusing

Nelo had had a more or less logical surfski assortment for a while. The model numbers from 510 to 560 were logical, showing the clear differences and categories.
The first confusion was the Vanquish which is supposed to fit between the 550 and the 560 somehow without following the earlier model number sequence.

But this year they really dropped the ball.
They came up with a new model numbering and products while still offering the old ones which made the whole product line very confusing.
They introduced the 62 (why not 620?) a model which was clearly an answer for the critics of their short boat concept.
They also introduced a model called 61. But it seems to be the same as the 62 only 10cm shorter. What is the point of that?
Now they also have a 52 and 54. These completely overlap the old 520 and the 540 models only without the bungee and by using bullet scuppers instead of bailers.
Can anyone see the bigger picture here?

Lower volume for lighter paddlers?

As they offer all their boats in 3 volumes ML, L and XXL it is not the reason.

They seem to like the name Vanquish -- they've used it also for their flat water kayaks. Something that obviously doesn't reduce the confusion ...
