I think the matrix weights can be daunting for some. Especially if you want to put in your plan , but a generic base to start from would be nice to ease newbs in . The AI plans are not that bad on defense but the offense has some clear weaknesses .
When I start a plan from scratch I will pick plays. Generally ones that will do good based off my weights . For a west coast offense specifically , the AI offensive plan isn't that bad but with the possibility of overusing one play even the AI is subject here.
To avoid this penalty after I pick my plays I set them balanced in the matrix by having higher or lower percentages based on how many types of plays . If I have 10 Short passes out of the 1-1-3 formation the settings for play calls there could be really high in comparison . Like a 40...and if I had only one long pass out of that same formation I would set that at like a 4. Just to avoid the abuse penalties .
I do this for all downs and all the matrix rates , run a game and adjust from there by looking back at my plays and see what my coach actually called for that game. If a play was called 10 times I will add another play with the same distance and formation to balance the calls 5 and 5 between them.
If you want to run in short senerios and pass long in long senerios simple adjust the settings but make sure you have enough plays to handle a few more similar calls out of that formation .
This is very basic but it will keep your calls in balance . The game play distance adjuster will search out of the designated ranges in your matrix to find plays with a higher setting. Same for slow down and hurry up...the higher they are will change the rates as well. It tricky even without going into more detail, and even more complex when rules are added.
