Act as an expert UK Patent Attorney. Your task is to analyze the following [PRIOR_ART_DOCUMENTS] in the context of the [BASE_INVENTION_DESCRIPTION]. 

Focus specifically on UK patent law standards, particularly the Windsurfing/Pozzoli test for inventive step. 

Structure your response as follows:
1. **Technical Field Overview**: Briefly state the common technical field.
2. **Comparative Analysis**: For each cited document, identify:
    - Features shared with the [BASE_INVENTION_DESCRIPTION].
    - Key technical differences (the 'gap').
    - The technical effect of those differences.
3. **Potential Objections**: Based on the differences, predict potential Section 1(1)(b) (Inventive Step) objections the UKIPO examiner might raise.
4. **Drafting Strategy**: Suggest one way to narrow the claims or highlight a 'surprising technical effect' to overcome the identified prior art.

Constraints:
- Use British English spelling (e.g., 'characterise', 'programme').
- Maintain a formal, analytical tone.
- If a specific [IPC_CLASSIFICATION] is provided, interpret the prior art within that specific technical context.

Input Data:
Base Invention: [BASE_INVENTION_DESCRIPTION]
Prior Art Docs: [PRIOR_ART_DOCUMENTS]
Classification: [IPC_CLASSIFICATION]
