Help with inconsistency

[emjimb]

Today had access to a launch monitor -using my 7 I ,(x22's 6.0 rifle ) this was the result -most swing speeds were in the 78 -81 MPH range :
179 181 165 167 171 143 132 129 176 155 152 138 161 145 149 161 148 173 165 143 149 129 171 168 162 143 ......
two observers see no change in my tempo or swing -some small differences shown in the launch angle category .So after 8 months of golf I have no real distance based on these results -making play tedious and difficult .I figure my 7 I for 165 on the course but as you can see I am long /short /on ??????.. how can I get more stable -I don't think that I am swing harder or faster to me -I am amazed because they all FEEL the same -the only difference i can feel is that on the longer shots my contact seems Softer ?? Thanks in advance for any ideas !
