Abstract: Systems, methods, and devices for providing an adjusted yardage recommendation (AYR) to a golfer prior to a golf shot. AYRs are determined based on predicted golf ball trajectories that are modeled from a golfer's golf ball launch data, using non-classical mathematical approximation methods. Each of the modeled trajectories are unique, and result in personalized AYR values that are personalized to each individual golfer, even where two golfers hit a ball with the same club the same distance while having two different ball flights. Devices that can perform the methods of the present invention include rangefinder devices and/or portable computing devices, such as a smartphone. Systems can include a rangefinder device and a portable computing device, in which the rangefinder device determines the line-of-sight distance and angle of elevation to a target and communicates the same to the portable computing device, which calculates the AYR.

Abstract: Systems and methods for candidate tracking and fee recovery in accordance with embodiments of the invention are disclosed. In one embodiment, a candidate tracking server system includes a processor and a memory storing a candidate tracking application directing the processor to obtain candidate data describing a candidate, identify at least one publicly available data source system, obtain public activity data for the candidate data from the at least one publicly available data source system, determine current employment status data for the candidate data based on the obtained public activity data, calculate fee opportunity data based on the candidate data, current employment status data, and staffing firm data, determine if the fee opportunity data has been fulfilled, and when the fee opportunity data has not been fulfilled, generate notification data including the fee opportunity data and metadata describing the employer and the staffing firm and provide the generated notification data.
