As a reference...;
Relative difference [(Test – Base)/Base] Use ‘% more/less than’ or ‘times more/less than’. · When using ‘% more/less than’: Five is 25% more than four; four is 20% less than five. · When using ‘times more/less than’: Five is 0.25 times more than four. Four is 0.20 times less than five
Treating relative differences as numerically symmetric: Five is 25% more than four. But four is 20% less than five – not 25% less than five.
