i got an 8.321 for 3x3, which i think is pr2 for me. here's the reconstruction
R' B R' F2 R F' R2 L' D F' R2 D2 B D2 F2 B' L2 B U2 F2
x' z // inspection
R' D' R' x' y' U' R' F D2 // cross
R' U R U' R' U' R // 1st pair
R U R' U' R U R' U' R U R' // 2nd pair

U R U' R' U' R U R D R' U' R D' R' U2 R' U2 // PLL
56STM / 8.326sec =6.73TPS
