@ -78,30 +78,23 @@ Here is the logarithm plot, with some smoothing applied:
![](https://nunosempere.github.io/rat/Circum-log-2.png)
And furthermore, a table:
blhah
Some of above in a table:
| Year | Rate of progress before | Discontinuity in terms of time of travel = New record - current record | How much extra time would have been needed? = (point - previous predicted point)/ previous rate of progress = (discontinuity - expected progress) / previous rate of progress |
|------|---------------------------------------------------------|-------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| 1586 | 1.1034 days/year | 237 days | 203 years |
| 1870 | 0.69 days/year | 525 days | 740 years |
| 1931 | 1 day / year | 13 days | 11 years |
| 1961 | 6.1 hours / year | 31 hours | 1 year |
| 1586 | 1.1034 days /year | 237 days | 203 years |
| 1870 | 0.69 days /year | 525 days | 740 years |
| 1931 | 1 day /year | 13 days | 11 years |
| 1961 | 6.1 hours /year | 31 hours | 1 year |
And here is that same table if we measure progress according to the logarithm (i.e., if halving the time needed is always equally impressive).
| Year | Rate of progress before | Discontinuity in terms of time of travel = New record - previous record | How much extra time would have been needed? = (point - previous predicted point) / previous rate of progress = (New record - previous record - predicted advance) / previous rate of progress |
