No, you have to think of a parcel of air that is at 1,000' and 11c, you then raise THAT parcel and it cools at the DALR (3/1,000) if dry or SALR (1.5/1,000') so if dry then raising it 1,000' it will cool by 3 degrees to 8C which is warmer than 7 so will continue rising i.e. Unstable, if Saturated it will cool even less so still be unstable, if the temp at 2,000' was say 9C then it would be conditionally unstable.

I think you are getting your lapse rates mixed up.
ELR is the ACTUAL lapse rate - 4C/1000' in this example
1.98C/1000' is the International standard atmosphere figure
DALR and SALR I think you know, though you did get it mixed up at the start of this thread.
