With Pachi, the winrate in this scenario would be 50%; our thread scaling incurs basically no strength loss compared to sequential playouts. This is visible in the Lousy Graph http://pachi.or.cz/root-vs-shared.png as second triplet of bars (labelled Sequential) vs. the last one, and in Fig. 9 of http://pasky.or.cz/go/pachi-tr.pdf (see text for detailed description of the graph).
