Doublescan decision depends on length of scanline, it does not care about number of lines (and it shouldn't). Scandoubling technically means fitting two scanlines in period of single "normal" scanline length.

Current test is: it is scandoubled if HTOTAL is less than 165.

EDIT: I guess there could be separate test if HTOTAL is larger but ratio of V vs H is bad enough..
