Somebody around these parts taught me this..
Sometimes after you make a change it can feel better you might like it better, but it isn't always guaranteed to be faster in the clock. I changed to a different spring package on time and it felt great to me, I liked it better. But lap times were -.5seconds slower after a 10 lap average.. So I changed back and tested again and again one day. 3 times over. At the end I the day I had confirmed without a doubt which package was better. In the end it was the stiffer setup that felt more aggressive and harder to drive in comparison.
Point if the post is.. Check your lap time average and test over and over, a lot. The times won't lie but going by "feel" will.
