Test of 20 minutes...

Hi, I'm currently training by heart rate. I took the test 20 minutes before starting the base.
Soon I will finish the base, need to do another test 20 minutes or this is not necessary?.
Some have told me that for training by heart rate is not necessary. Trained by watts if that would be necessary for training short series of high intensity.
What should I do?. The ideal is a potentiometer, but I can't buy at present.
Thanks!

However, that is only if you recorded correct info.
Positive improvement could be shown by a further distance travelled in 20 minutes, a lower average heart rate over the 20 minutes for example.
