How much Germany Bell Beaker ancestry in the Guanches?

[Philjames100]

Olalde et al. (2019) and Villalba et al. (2021) have Germany_Bell_Beaker as the source of steppe ancestry in Bronze Age Iberia, as well as the source of R1b-M269 lineages which replaced Iberian Copper Age Y-DNA lineages. According to Fregel et al. (2021), the Guanches had steppe ancestry, and previous studies have found that they had R1b-M269 lineages with frequencies ranging from 10-44% depending on the island (Ordonez et al. 2017, Fregel et al. 2009). So does anyone know, or can they work out, how much Germany_Bell_Beaker ancestry the Guanches had?

I have 2 German BB samples and 4 Guanches in acceptable quality.

Completely different populations.

When it comes to PCA the Guanches are between ancient Roman and modern Berbers/Tunisians/Moroccans and the German Bell Beakers are near Unetice, BA Denmark, Celts and Battle Axe. Far distant. Greater distance then WHGs have from Anatolia HG, because of the large North African component in Guanches.
