In the old hitfinder, deconvolution is done seperately in the time and pad directions. The switches that control the time deconvolution are TRFF and DECON.

Take a look at some of the spectrum fragments shown here, deconvoluted with the three switch settings listed above.

What I see is that TRFF=2 and DECON=2 either (1) fits a little better than TRFF=1, or (2) fits a lot worse. Case (2) is fairly rare, but you will find some examples below. When TRFF=2 fails, it does so spectacularly. However, this happens when the pulse is wide, and the TRFF=1 peaks are rejected for being too wide. So, I don't know conclusively which is better.
