I tried toss bombing and i cant get it to work from longer distances

So i watched this youtube video about toss bombing and it told me to pitch up and drop your bombs when you reach your bases

Well i tried it and i have to go pretty close to be able to toss bomb correctly wich just defeats the purpose of toss bombing entirely

(Also im using the F-4S for context)

It’s a lot easier with a ballistic calculator. Pretty much impossible from range without one.
