Yes but they allow to 240 peak temp which is high. 220 should be max and
the liquidus is 179 deg C not 200. This concerns me. I think they are
recommending one profile for all boards.

I don't think the peak is necessarily high, if you are in the lower end of
that range. 215 - 218 C is about normal for my experience for a peak, and
45
seconds above liquidus seems normal.
