Hello and welcome. I am a bit taller than you, but find the "ideal weights" to be ridiculous for someone of my build. When I was 170 I was skinny as a rail, but still considered overweight on the charts!
In any case, it is good to have mini goals, as the larger ones can be overwhelming and discouraging.
And actually, technically I am not "in" this group any longer either, but I still post here!
I wish you the best.
