To be fair: take this methodology that was developed years ago but apply these specific cutting edge methodologies to improve it gives you much better code in a day or two than any scientific code I've ever seen published by affirmed researchers in the field. You get the code, documentation and tests. Is the code easy to maintain? Most certainly not. Is code published by scientists maintainable? You're lucky if it even runs. You take that and you have a partially working solution, you spend a week rewriting it and you have a working better methodology that would likely have taken you a year to develop.
