I doubt it took Obama an entire day to play a round of golf, anymore that it does Trump (Trump has an edge since he drives a cart everywhere, including on to the greens). On Aug 1 of his presidency Obama had played 11 rounds, Trump has played 21 so far (a number that might near 40 after these 17 days).  But the issue would be so glaring if Trump hadn't criticized Obama so heavily for even taking vacation and promising himself that as President Trump would "never take a day off".
