SF L at a horse riding competition stands for "Sans Faute au Chronomètre" in French, which translates to "without fault against the clock" in English. This means the horse and rider completed the course without knocking down any obstacles and within the time allowed. SF V, on the other hand, stands for "Sans Faute en Vitesse" in French, which translates to "without fault in speed" in English. This means the horse and rider completed the course without knocking down any obstacles in a speed competition. **

To draw a Sankey diagram, start by identifying the categories you want to represent and the flow of data between them. Draw a horizontal line to represent the total flow of data. Then, draw rectangles of varying widths to represent the different categories, with the width of each rectangle corresponding to the amount of data flowing through that category. Connect the rectangles with arrows to show the flow of data between categories. Label each category and the flow of data to make the diagram clear and easy to understand. **

SF (square footage) classes accumulate in leasing based on the size and quality of the space being leased. Class A buildings are typically the most desirable and highest quality, with the newest amenities and technology, and are usually the largest in terms of square footage. Class B buildings are of slightly lower quality and may be a bit older, while Class C buildings are the lowest quality and may require more maintenance. The square footage of a building is a key factor in determining its class, with larger and more modern spaces typically falling into the Class A category. **
