Redcode 28 vs. Redcode 36

[nacamera]

Can anyone please give me an in depth explanation as to what is the difference between the 2 flavors of Redcode. Yes, I can already guess that Redcode 36 is "better" (higher numbers of most things are) but there has to be some reason why 28 is the default. What are the advantages and downfalls of each? I'm not an engineer, so please be kind in your syntax selection.

Thanks,

Main advantage to 28 is enabling 4K 16:9 recording to CF card. Similarly, it will give you slightly higher maximum framerates for varispeed.
