does the racing line slow you down?

i used corners only for braking and im slowly starting to turn off racing line, just need more practice for consistency and i've noticed that i feel like i carry more speed through the corners going by my braking points, i havent been able to improve my lap because im not able to consistently do it yet but i tend to go green on my TT sectors easily when i nail the corner (i may also have removed the distraction and am now actually focused on my traction/line ect

for example, turn 1 australia i feel way more confident at now then i was before
