I'm not the fondest of documentation neglecting questions from people who seem to know their way around but this is always going to come down to reading the selection index and what is around it. You already know it. You can split special match circumstances into an array and match against them before providing a solution but you already seem to know that.
I have never done this before. The code that I have so far was given to me through lost of help in this lovely forum. I just wanted to make sure I was on the right path before I hard code 300 words. Looks like I can proceed?
Thanks for your confimation. I'll try it and come back if it didn't work
There's always a better way to do things but ultimately it comes down to if what you're doing works for your audience. If it does, the majority would say you did it correct. After you did it correctly you can spend time optimizing it however you like. If you get down to those specific questions be sure to provide a sample and some code that you think needs optimization and I'm sure we'll be able to help. You're welcome and good luck!
