See the complete statistical results from these tests.

The SARE patternator captured significantly more spray material than the Cornell patternator on all panels except the bottom panel (#1) that was positioned at 1 to 2 feet off the ground. The top panel (#7) was significant at the 5% level while the 2nd through 6th panels were significantly different at the 1% level.

The addition of screens to the SARE WITH SCREENS patternator did not provide any improvement and actually decreased its efficiency slightly. On the top (#7) and bottom (#1) panels there was no significant difference with the Cornell patternator. The 2nd and 6th panel were significant at the 5% level, while the panels in the middle (#3,4,5) were significant at the 1% level.

There were some significant differences between the SARE patternator and the SARE WITH SCREENS patternator. On the top panel (#7), significantly more spray material was captured at a 5% level of significance by the SARE patternator. The same result was found on panels #3 and #1.
