It is likely that the only way PPLE can become government party is to win outright, so here's my estimation of PPLE's "Road to 251", estimating 201's most likely constituencies for them to win to govern the country.
Bhumjaithai's Road to 251 appears to be a more tricky one. Even with party's strategy solely betting on constituency seats via attracting local machines, they are still required to win 100+ more seats to govern solely as the government.
