Hello Everyone,
This is just out of curiosity. What is duration difference between a computer generated report and a manual report? I mean the error introduced by either method in their calculations. Does a computer generated report introduce a slight error? Or does a manual report? Moreover, approximately, in general how long is the difference in time duration error?
Thank you to the senior astrologers who would see this due their extensive experience. Thank you to everyone else too for sharing their insight.
Just a few short notes for perusal by members here, if I may be permitted to add:
Any measurement (or calculations in present context) is aimed at deriving the TRUE value of something.
The closer to TRUE value, such measurement is determines its level of accuracy.
The more detailed the measured value is determines its level of precision.
If the sun's longitude is stated as 16 degrees 20 minutes and matches the actual value in degrees and minutes, the measured value will have an accuracy of 100% and 0% error.
At the same time a stated value of 16d 20m 5sec would be precise up to seconds. Same accuracy, greater precision. 16d 20m 5.3 sec would be even more precise.
These terms are not limited to numerical values but also qualitative observations and descriptions!
An orange is a round object is accurate.
An orange is a round fruit, orange in colour, having pitted skin, sour-sweet taste with a protrouding tiny node at its pole will be accurate and more precise.
The accuracy of computer generated values (for planets, for example) would be determined by how accurate the formulae/equations, algorithm and code is and the accuracy and precision of the computer.
If the code is defective or not right, the software will make the calculation error, consistently (systematic error). Such errors when caught can be fixed by correcting the calculation routine, algorithm, etc.
Calculation by hand (traditional way) would be subject to a similar accuracy in the equations etc used. However, due to human error, there is the possibility of making an error. This would not be a consistent error but a random error, which makes it more difficult to trace.
The default values chosen (parameters) such as ayanamsha, house division system, etc would further introduce a variation in the output.
Computer-generated reports (interpretations!) generally depends on the software identifying patterns and combinations and matches those with yogas, other astrological combinations, and using 'descriptive text strings' prepares a *report*, generally, one factor or one combination at a time and can result in a wordy but confusing prose!
One commercial software managed to try something more complex, pretty nicely, but for some reasons, it was pulled-out from subsequent sub-sub versions which generally indicates a minor change. In this case, I think the change was MAJOR!
