25% faster is 1.33x work done in the same time. What you want is 0.75^7 (almost 2 years) gives you 13.3% of the original time, which is 1/7.5. Only it was more like 25-30% so I rounded up.
Interesting how people interpret the word faster differently.
To you, 2x faster means 2x the work done in the same time, but 25% faster means 1.33x the work done in the same time.
I see this a lot - in software people interpret 50% faster as a 50% reduction in time taken.
If a car is 50% faster, I hope people would universally interpret that as e.g. 20 to 30 mph. But if I asked people how long would a 1 hour journey take if it were 50% faster, I bet a lot would say 30 mins, because it kind of seems like that's what I mean.

50 percent faster is 2/3 time, but yes, prominent people have made this error and even doubled down on it publicly.
