If Vx is required, maybe the planned departure is a not good idea at all.
In most SEP, at sea level max performance you are looking for 1:6 with Vx vs 1:8 with Vy (better numbers can be derived from POH as max ROC/VX vs max ROC/Vy assuming ROC remains same on both), on hot days, you are looking at 1:10-1:15 for both
Definitely, not a good idea to play 1:7

That’s because you speak proper English For us non-natives everything is clear we speak like that or worse
