How to read the charts

The chart shows the best frequency to use. The "hotter" the slot, the higher the probability of making the contact on that band.
These are based on CW, 100W, dipole to dipole and a "good" reception. Adjust the reliability according to your own station. CW (Morse) offers a big advantage.

Reliability/Band graph produced by VOACAP Online
This shows that to work the eastern USA-based stations from the UK, 20m (14 MHz), 17m, (18MHz) and 15m (21MHz) are your best bets.
In the early hours 7MHz or even 3.5MHz are the best bands. I have never worked any IMD stations on 30m (10MHz).
