A soft-typing is an informal look at a person's vultology, typically in under five minutes and without checking signal strengths through the assistance of a tool like the codifier. A soft-typing is therefore qualitative, and is a general first impression given off by a person. Even with proper training, an informal analysis of this kind will be off the mark ~30% of the time, as it does not check all variables thoroughly enough to be sure of what a person's type may be.
A formal-typing is the process of tallying-up the strength of visual signals, making sure all data points are checked, then ensuring a proper weighting against each other for a comprehensive conclusion. A formal-typing typically cannot be done in less than 30 minutes, and typically takes about 1 hour or more to export out a PDF report with all the signal information. A formal typing can also include a GIF Breakdown, where specific timestamps are noted alongside GIF examples of signals, composited together into a document that shows the type.
When it comes to knowing your type, rigor matters. The difference between an informal analysis and a full type report is like the difference between a brief doctor checkup and a full blood panel. Even for an experienced vultologist, someone's type and development cannot be fully confirmed without checking all 70+ signals meticulously, and each signal's strength levels from Low/Medium/High. Confirming type this way, which can attain 90%+ consensus among independent readers, takes time and expert training. Only a full report can attain certainty of type, and certified vultologists go through weeks of training and have to pass a certification exam, ensuring proper practice methods.
Unfortunately, no matter how talented of a reader a person is, all the necessary data often won't manifest without checking around 20+ minutes of footage in great detail. A five minute analysis may not possess all the needed information to draw the right conclusion. It's also unlikely that a reader can hold all 70 signals in mind, and properly weight their levels in their mind without the assistance of a tool. As such, errors are bound to happen even for the most experienced readers.
Speed is also not the highest priority to have when aiming to determine something innate about yourself. While it may take longer to figure out one's type this way, a thorough look at your visuals will ensure that the classification doesn't shift in the future, aside from perhaps a change in development, as you also evolve through life.
