What I always do when using my guides:
Given any camp that can't be outright cracked with 1 single wave ...

I first simulate a wave of 250 or , then see what's left.
I then typically go for Wave 2 with an MMA or Major, depending on whether there are low HP units or not. That wave I load with a mix of and and try to adjust upward or downward.
If the amount of lost looks fairly low, I will see if I can already save troops on W1, if there's no way in hell freezing over to not lose , I introduce a wave either before or after the first. Usually, I introduce a MMA Suicide wave before the first and see if that helps.

In calculating the amounts of troops, I use a method called "binary search", so for example if I would simulate with 100 150 and see I lose cannons, I go to 170 90 , and see if I still do. If I don't, I try 135 135 , and up and down until I got the perfect number.

It usually takes about 2-3min to simulate a camp. I don't claim my solutions are always optimal, but I figured that given my losses for no-block VLT are just about 5000 troops , I am probably doing something right.
