Adding A Certain Number of Rows w/ Prefilled Cells

I am hoping to automate my spreadsheet to add rows as needed for testing upon failure.
In my example, if my result hits 0.19 or higher, I need it to add a number of rows equal to the value of the sample number that failed. Following the example, since row 6 was 0.2, it added 6 rows and prefilled the Sample Number cells with the equation to determine the sample number.
I understand macros in theory, but I'm not sure how to piece all of this together. I appreciate any help you can provide!

This made me realize a problem with my logic, thank you. I need it to have a total of 10 blanks following a failure, which works if it fails once, but not multiple times. Is there a way for it to count the remaining spaces then add enough to get it back up to 10 spaces following any failure? To use Millz example inquiry:

Sample Number	Result
1	0.188
2	0.190
3	0.188
4	0.191
5	0.187
6	0.200
7	0.155
8
9
10
11
12
13
14
15
16

This is perfect, thank you!
