FTV Scoring Explained

## What is FTV Scoring?

- It is an alternative competition scoring formula for dropping competitors scores over a multi-day competition. It is used in place of dropping your lowest scoring tasks in favor of dropping some percentage of your lowest PERFORMING tasks. PERFORMANCE is measured by the amount of points you got for the day versus the maximum available points for the day.
- FTV = Fixed Total Validity. This refers to the fact that a percentage of validity is used to calculate the total points available. Essentially you add up the validity of each task in the comp then subtract whatever percentage of FTV is being used from that sum. So a 4 day comp with validities of 100%, 75%, 50%, 100% would have a total validity sum of 325. If FTV percentage == 50% then the FTV value of the comp would be 325 - (325*(50/100)) == 162.5. If FTV percentage == 25% this mean we are DROPPING 25% of the validity (not keeping) so we'd get 325 - (325*(25/100)) == 243.75 as the FTV for the comp. More on how this is used later.
- Instead of looking at your lowest score and dropping that it looks at your performance each day and drops your lowest performing days. Performance rating is calculated by dividing your score for the day by the validity of the day, so if you won the day on a fully valid task it would be 1000 points/100% valididty == 10 points of performance

## Advantages of FTV over Dropped Tasks

- The most obvious advantage of FTV is that it will reward high performance on lower value days rather than just dropping low scoring tasks. This means if you flew well on low validity task you will keep this score and instead be able to drop points from a task where you didn't fly as well compared to the rest of the field. Therefore FTV rewards all flying days and skilled flying more than just dropped tasks.
- Because FTV handles point percentages for a task it can easily handle competitions that have mismatched days in comparison to the FTV or dropped task count. For example in a friendly league it's common to drop every other task which is equivalent to an FTV of 50%. However if you have 9 tasks then you can't just drop half a task so we generally round up and keep 5 tasks and drop 4. In FTV this is no problem because it can drop the points for half a day. This is great because it more accurately sums the points for the competition in the spirit of the FTV percentage allotted.
- Pilots don't need to wait until they reach X number of tasks before they see the benefit of dropping points.

## Disadvantages

- It's complicated, to properly calculate your FTV scores, you need a freaking spreadsheet. Perhaps this could be alleviated by pilots understanding the system better and having more information about the calculations on the score sheets.
- If the competition has 100% validity you won't notice that much difference between FTV and dropped task scoring EXCEPT when the number of days is not evenly divided by the dropped percentage.
**On mariginal or dangerous days, it could cause comp pilots to push harder and longer knowing that these days will count just as much as 1000 point days. The onus will be on the safety committee in FTV events to stop the task early to avoid dangerous racing!**. In straight dropped tasks, most pilots would realize the day will be devalued and that the task will likely be dropped regardless of their performance so better to play it safe. However, the safety committee should be less hesitant to stop tasks knowing that the points will still be used in the final comp calculation.

## Formula Explained

Please see the bottom of the page for detailed examples of the formulas and how they are used.- Decide what
**FTV Percentage**you want for your comp. 50% is like dropping 1 out of 2 tasks. 25% is like dropping 1 out of 4 tasks. - Add up the validity of each day for the competition, this is our
**Total Validity**. - Obtain our
**FTV**by subtracting our**FTV Percentage**from the**Total Validity**. FTV = TotalValidity - (TotalValidity*(FTV Percent/100)). - Now let's get a
**Performance Score**for each pilot and for each of their tasks. This is done by dividing their**Task Score**for the day by the days**Task Validity**. Therefore a top performance score would be 10 given a winning score of 1000 and a day validity of 100% - Since we want to DROP the lowest performing days for each pilot, we next sort each pilots tasks by their
**Performance Score**from best to worst. - Here's where it gets tricky. We are going to take our FTV score (step 3) and subtract the days validity from it until we have no FTV left. If the remaining FTV > TaskValidity the pilot gets their full points for the day and we subtract the days validity from FTV and use that remaining value in the next highest performing day. If the Remaining FTV <= DayValidity we calculate a percentage of the pilots score to be used as follows: taskScore * (remainingValidity/taskValidity), then set RemainingValidity to 0. If RemainingValidity = 0 then just completely drop the task.
- So to summarize, pilots will get to keep all of their top performing scores until there is only a small remainder of validity left. At this point the next highest performing task will return only a percentage of points, then all lower performing tasks will be dropped.
- That's it, we just sum up all the scores that we kept and that's the pilots competition score.

*Try setting FTV percentage to 25% and dropped tasks to 4 (common comp settings) and notice that pilot 3 wins in FTV but loses in dropped-tasks. Notice that pilot 3 has more high performance days then the other two but has one low day.*

FTV Percentage: %

Drop one task for every tasks.

FTV = [totalValidity - (totalValidity*(ftvPercentage/100))] = [ - (*(/100))] =

Now let's compare what the event scoring looks like between FTV and Dropped-Task
