Bitrix 24: Support Median Response Time

PCMAG is treated as a single opinion by aggregating its three data points (1920 at 0.90, 960 at 0.95, 4320 at 0.60) into a weighted average ≈ 2135.51 minutes. TechRadar provides a range (1440-2880) for email support; we use the midpoint 2160 minutes with confidence 0.90. We then combine the two opinions using their effective confidences (PCMAG ≈ 0.817, TechRadar 0.90), yielding a final value of about 2148 minutes.
