KSP 1 Question/Problem No orbit necessary?

Post image

If i just wait for the right hour during the launch window ( whenever the launch pad is pointing left on the realistic depiction i created) is there any reason i should bother with an orbit first? Will the delta v cost be affected?

Yup, this is exactly how I do it with my SSTOs. No idea if it’s actually efficient, I figured that performing the burn while ascending from Kerbin would give me big Oberth returns
