I know that there is some kerfuffle over point inflation. While there have been manufactured inflation to try to steer production onto certain hardware, E.G. Big Adv I think was the WU's designed for multi-core CPUs (back when dual core was still a novelty.) These WUs gave mad points to anyone willing to run multi 16 core CPUs. Guys had awesome 4-CPU x 16 core rigs that cost lots of money. The experiment didn't work in the end and GPUs took over that space.
But inflation overall had to happen. The WUs we got in the CPU only days would take a few days to complete. Todays machines would take a few minutes with current GPUs. While we could keep the points the same and just crank out hundreds of WUs a day, the WUs got more complex. So F@H implimented several straegies over the years to calculate equivalent scores. At any rate, I do find it fun to look at what we had to do back in the day but every day turns into a new day and that's just the way of the world. Points are points and I try to earn as many as I can based on my comfort level to produce those points.
