• Measure toe-to-heel or toe-to-toe?  PARS is based on a toe-to-toe measurement.  How far did they jump?  How far did their nose travel?  Their toes?  PARS records and tracks the distance to track distance changes over time.
   
• Size matters:  This test score is based on jumping greater than the length of the Boxer's foot or twice the Boxer's foot length.  So, coaches need to know the length of their Boxer's feet! 
   
• "4" doesn't tell the whole story:  A boxer who can jump 36 inches will score a 4, the highest score.  In their next assessment, they could jump 25 inches losing distance or 48 inches gaining distance... but, either way, by FAB scoring, they are still a 4.  The paper FAB scoring sheet didn't ask for the distance jumped.  PARS does.  This way coaches can see from assessment to assessment whether the Boxer is doing better or losing ground. 
    
• Bonus Points:  To tell the story when a 4 is better than 4, on the Boxer Profile, PARS awards extra credit.  Bonus Points are awarded when a fighter jumps 3 or more times the length of their feet.
    
• SKIP:  If a Parkinson's fighter cannot perform the Standing Jump due to Parkinson's issues, their score is a zero.  However, if they cannot complete the Standing Jump due to bad knees or a bad back, choose SKIP.  A test that is skipped is ignored for scoring purposes so PARS does not confuse Parkinson's symptoms and limitations with problems your fighter may have as a result of a bad back, bad knees or being 94 years old.

Size matters:  So, I've measured more than a hundred Boxer's feet.  Mostly because they don't know how long their foot is and the standing jump requires a coach to know when they jump more than the length of their foot or twice the length of their foot.  However, everyone knows their shoe size.  So, we found a shoe manufacturers conversion chart for men and for women converting shoe size into foot length in inches.  Within PARS, by knowing the Boxer's shoe size, the app can look up the length of their foot within a quarter inch and do the calculation for you.  Pretty cool.

Sometimes 4 is better than 4.  So, a Boxer jumps 36 inches during their intake assessment and scores a 4.  And coaches can tell they have earned a 4 without measuring their actual foot because even if they are a 7 foot tall NBA player, their foot is not more than 18 inches.  In their next assessment they might jump 44 inches and they would be a 4.  A better 4.  Or, they might jump 25 inches and still be a 4.  A worse 4.  So, the standard FAB scoring does not tell us if the Boxer is improving or if they are declining until they fall below twice their foot length.  Knowing their shoe size, the app looks up their foot length (within a quarter inch).and divides their jump distance by their foot length coming up with a Jump/Foot Ratio.. If a Boxer with a 10 inch foot jumps 36 inches, their Jump/Foot ratio is 3.6 which is more than 2 so they receive a 4 as their score. In their next assessment, if their jump is 42 inches, their jump/Foot Ratio is 4.2 so they still score as a 4 but the coach knows the Boxer has improved, but, if their jump falls to 28 inches, their Jump/Foot Ratio falls to 2.8.  They still score a 4 as the FAB score but the coach now knows they have declined.  In either case, the Boxer knows how they are really doing.

Bonus Points:. So, now that we have better data, we need a better scoring system.  PARS gives Boxer's bonus points in their BwP FAB Score for Boxers who score a 4 to indicate improvement or decline in their distance jumped.  A Boxer who gets all 4s in the FAB would normally receive a 100 for their FAB Score.  But, based on their standing jump, they might score a 104 this assessment and a 106 (improved standing jump) or a 102 (declining standing jump) in their next assessment.  Note: PARS also gives bonus points for the TUG and the S2S.
