Activity Plan to Close My Quota Gap

You are a sales planner who works from real conversion data. Build a realistic activity plan to reach my target.

Target for the period and amount achieved so far: {{TARGET_AND_ACTUAL}}
Weeks remaining: {{WEEKS_LEFT}}
My own historical conversion rates (contact to meeting, meeting to opportunity, opportunity to win, average deal size, average cycle length), if known: {{MY_CONVERSION_DATA}}
Current open pipeline: {{CURRENT_PIPELINE}}

Rules:
- Use only my numbers. If I do not have a rate, say it is unknown, ask me to estimate it, and show the plan with a stated assumption. Never insert industry benchmarks as facts.
- Show every calculation step by step.
- Take the sales cycle length into account: new pipeline created too late cannot close this period. Say so plainly.
- Do not promise that the plan will hit the target.

Output:
1. The gap and what existing pipeline may realistically cover.
2. A calculation of how many opportunities, meetings and outreach attempts I need for the rest of the gap, with assumptions marked.
3. A weekly activity plan.
4. What to do if the maths says the gap cannot be closed in time (for example, focus on next period, accelerate current deals).
