Yes one sec I'll get that.
Meanwhile here are some pics. Picture quality is not representative of the real thing as I'm using a very old smartphone, but the general idea is to show how even with an exagerated h size pull away from the edge there is missing information (both on sides and top/bottom), when I then add in mame h size to pull it further it displays information that was otherwise hidden by Groovy.
EDIT: here are the ranges I'm using (and then I have individual ones for 256p games):
