You can use the auto function on the SMS1 for starters, but should not stop there.
By tweaking the curve you can surely enhance the curve more.
And bear in mind that the SMS-1 can hardly be used beyond the crossover frequency; it can show the curve until 200Hz but it can't control the higher part.
In fact, I had a nasty 100Hz +18dB bump I tried to get rid of, and had to dial in the EXTRA crossover filter inside the SMS-1 (on top of the 990 filter) with a 32dB flank steepness to prevent the 100Hz bump to be output through the sub...
There are also discrepancies in the actual amplitudes of the bumps and holes shown on the screen- always try to use your ears to confirm what you're seeing...
This is partcularly so around the crossover frequency, my room has a bump at 67Hz which hardly reared it's nasty head on the TV, but was in fact very audible.
So I ended up setting an extra -12dB EQ on that frequency, which made the display worse but the sound better!
Remember, the SMS1 is only a tool, not a miracle.
