Recommendation engine

In a system implementing a computing device and a swing sensing device, a method comprising:

• a. receiving, via the computing device, first data characteristic of a swing of a user generated by the swing sensing device;
• b. calculating, via the computing device, second data based on the first data, the second data including an attack angle and a shaft lean;
• c. determining, via the computing device, an overall bounce factor based on the second data;
• d. transmitting, via the computing device, information indicative of a bounce recommendation based on the overall bounce factor.

A system comprising:

• a. a swing sensing device configured to obtain data corresponding to a characteristic golf swing based on multiple swings of a user, the swing sensing device further including:
• i. a sensor configured to obtain the data corresponding to a characteristic golf swing based on multiple swings of a user, and
• ii. a transceiver configured to transmit the obtained data corresponding to a characteristic golf swing based on multiple swings of a user;
• and
• b. a computing device configured to determine and transmit a bounce recommendation based at least in part on the data corresponding to a characteristic golf swing based on multiple swings of a user, the computing device further including:
• i. a transceiver configured to receive from the swing sensing device the obtained data corresponding to a characteristic golf swing based on multiple swings of a user,
• ii. a factor determination module configured to determine an effective attack angle based on the data received from the sensor,
• iii. a memory device configured to store information defining a recommendation set, the recommendation set correlated to effective attack angle, and
• iv. a selector configured to determine the bounce recommendation from the recommendation set based on the determined effective attack angle.
