I would like to assign ascending count for observations above certain value by id and start with the first observation of the id by 1 regardless of the value and continue the count if value is above 5 the output would be like:
| id | days | event_count |
| A | 1 | 1 |
| A | 5 | 0 |
| A | 2 | 0 |
| A | 4 | 0 |
| A | 7 | 2 |
| A | 5 | 0 |
| A | 8 | 3 |
| A | 2 | 0 |
| A | 1 | 0 |
| A | 16 | 4 |
| B | 1 | 1 |
| B | 5 | 0 |
| B | 2 | 0 |
| B | 4 | 0 |
| B | 7 | 2 |
| B | 5 | 0 |
| B | 8 | 3 |
| B | 2 | 0 |
| B | 1 | 0 |
| B | 16 | 4 |
| B | 4 | 0 |
| B | 5 | 0 |
| B | 3 | 0 |
| B | 4 | 0 |
| B | 7 | 5 |
| B | 8 | 6 |
| B | 8 | 7 |
Thank you.
