Really the only option they had was to rely on something called dead reckoning, basically figuring out where you are by estimating your speed and compass heading to plot your journey.

Essentially, they took these other measurements and predictors, like percent rep max between group rep differences, velocity loss, and RPE, and then using subjective calculations, they equated a corresponding estimated reps in reserve.

基本上，他们采用了其他测量和预测指标，比如一组内重复次数差异百分比、速度损失和主观用力感（RPE），然后通过主观计算，算出相应估计持续重复次数。

The reason we think that is that using modern computer techniques, you can wind back the night sky and say, " Where would the moon have been? Where would the stars have been? "

因为通过现代计算机科技模拟，我们能算出过去夜空，得知当时月亮和星星位置。

There may be an interesting way to solve this riddle: We just take our exponential clock and extrapolate it back in time, to the simplest conceivable life form – something equivalent to a being with a genome containing just a few letters.

可能有一种有趣方法来解决这个题：我们只需利用指数时钟并将其回过去，算到最简单可想象生命形式——相当于基因组只包含几个字母生物。
