Nice feature, but for E-V13 it suffers from the usual shortcomings, mostly dictated by the lack of ancient samples and modern samples, especially from specific regions.
Like the centre for the early E-V13 distribution being guessed around Shkoder, whereas much of Bulgaria-Romania being largely left out even in the later periods. The British Isles being reached about 1.900 BC, whereas most of Romania-Moldova was reached only in the La Tene period! This is of course absurd, because in the La Tene period they were rather pushed back, not newly spread to those areas of Northern Romania and Moldova.
The most obvious reason for this is the lack of Eastern samples, especially from Romania-Moldova-Western Ukraine in the prehistorical period and modern testers, whereas there is a strong testing bias towards the British Isles in particular.
I can imagine E-V13 to have appeared on the British Isles as early as with Urnfield-related migrations, but surely not earlier and rather later, especially for the great majority. The lack of ancient samples plus the strong British bias in combination cause therefore a significant distortion.
Here the position of E-V13 in the tool around 2.500 BC:

It is is easy to spot the most obvious problem, which is the positioning is much too Western. The North-South axis is at this point much more disputed then the East-West one, because it is pretty clear we are dealing with a centre between the Tisza river basin and the Lower Danube basin. The question is whether its either or one at this early stage.
Anything West of the Central Balkans can be excluded.
I think this has some implications for all haplogroups, because the tool as such looks nice and largely correct, but it can just work with the available data. If there is a lack of ancient and modern unbiased sampling, the result can't be 100 % right.
But its a great tool and I expect it to become more accurate with more ancient and modern samples. Its already much better for many branches than things were on other tools some years ago. Even just 2 years ago, things looked worse.
