Up to now on this sequence, we’ve checked out the unit of oil and the operation of Brunswick lane machines. On this ultimate article, we’ll put all of that data collectively and talk about intimately what Brunswick presents on their oil sample sheets. We’ll be taught extra concerning the machine’s options as we go and learn how to interpret the graphs and tables which are supplied on the sample sheets.

A Brunswick sample sheet in its full kind is proven in Determine 1, which exhibits Brunswick’s Phantom oil sample. It was downloaded from the Brunswick online pattern library, the place you will discover numerous different patterns, too. They give the impression of being considerably completely different from Kegel’s oil patterns, however keep in mind, as we noticed final time, the machines work in a really completely different means, and the sample sheets mirror that. Like Kegel’s oil sample sheets, Brunswick’s sample sheets have been up to date over time, each cosmetically and to mirror advances within the lane machines themselves, however the data they supply is identical throughout all variations.

We’ll now break the sample sheet down into three sections, which we’ll talk about intimately under.

Part 1: Normal data

Proper on the prime, we see the Brunswick logos and their hyperlink to the PBA. Direct+ Conditioning system (mentioned in the previous article) is the identify of the system that Brunswick makes use of of their machines, and relevant lane machines are proven on the proper. The Envoy and the Authority22 are listed on this instance, however on newer sample sheets, the MAX machine is proven right here as nicely.

Determine 2: The primary part of a Brunswick oil sample sheet.

Beneath this prime row of logos and relevant lane machines is details about the sample itself and the atmosphere that’s being created. I’ll undergo every field right here for completeness, regardless that some are self-explanatory.

Sample data

Date: This lists the match date, or maybe the date the sample was created.

Sample sort: The class of sample—sport, problem, or leisure—as per the USBC definition, which depends on the side-to-side ratio of the oil sample. Sport is lower than 4:1, problem is between 4:1 and eight:1, and leisure is larger than 8:1.

Sample issue: Excessive for sport, medium for problem, and low for leisure.

Sample designer: The identify of the person(s) or group that has designed the oil …
