Deviation impact on GBP/USD
Readers can find FX Street's proprietary deviation impact map of the event below. As observed the reaction is likely to remain confined between 10 and 70 pips in deviations up to 3.5 to -1.5, although in some cases, if notable enough, a deviation can fuel movements of upto 100 pips.

How could affect GBP/USD?
A solid retail sales report could help the GBP to regain footing on a sustained basis, allowing the rate to surpass 1.30 barrier. While a worse-than expected print would knock-off the pair back below 1.2900.
In terms of technicals, a break above 1.2992 (7-month high) could lift the pair above 1.3050 (psychological levels), beyond which a test of 1.3400 (round figure) is imminent. Conversely, a break below 1.2926/21 (5 & 20-DMA), leading to a subsequent break below 1.2872 (May 15 low) is likely to drag the pair towards testing its next support near 1.2842/29 (May 12 & 4 low).
