for Digital Nomads Designer vs Harvest: What You Need to Know

# benchmark_time_tracking_accuracy.py
# Benchmark time tracking accuracy for Designer vs Harvest under intermittent network conditions
# Methodology: Run 100 1-hour tracking sessions, force network drop every 10 minutes
# Hardware: MacBook Pro M2 Max 64GB RAM, macOS 14.5 (23F79)
# Network: 1Gbps fiber, forced drops via pfctl
# Dependencies: designer-client==2.1.4, harvest-api==7.8.2, requests==2.31.0
# Designer Python client: https://github.com/designerapp/designer-python-client
# Harvest Python client: https://github.com/harvesthq/harvest_api_python
