.5qt sump extension - correct oil level?

[Oldcarguy]

Just to confirm, after I install my .5qt sump and oil pickup extensions, I continue to run at my current indicated oil level (usually the top two or three bars on the indicator blank). If I understand correctly how the level is measured, i’ll have ~.5 quart more oil in the sump at any given measurement (with .5qt additional at oil change). Correct??

Thanks in advance.
