Great job Jim!
Your flow is the same as I use. Have two xlights running, run through the source sequence , see what it looks like on their house. Decide what models from their sequence that will match your own house.
For example when we mapped the sequences Lilia did on our house, we had 22 arches. We were moving the seuqnce to Dave Pitts house, he had only 10 arches. Some of the sequencing Lilia did started with our Arch 7 and did effects both directions. We then decided to map our Arch 7 to Daves Arch 3.
The point is , look at the source and imagine moving those effects onto your house. It can be that our arches will go to your eaves.
I think this is the hardest part. When Lilia does this for a client, she makes a list to map source model names to target model names. When this paper list is complete then she uses the "import, Sequence" to build the mapping file.
again, great job!
