Well, my experience with play mode 'normal' and shell drift is:
a) RADAR is much more reliable than you think. At most, at strong wind adjustments by +- 0.1 or 0.2 (not more) are required. My hit ratio with RADAR is > 95%. Thus it would be helpful if the coarse tuning could be skipped and only fine tuning is needed - if at all.
b) The shot history markers are most useful for shore bombardment with both static targets and stopped ships. With moving targets and gun platforms ... well ...
But meanwhile, my hit ratio without RADAR is not too bad after all.
