I'm no longer associated with a flying club having left the industry for a break. Back then i believe that it was 70 hours P1 before the test could be taken. Perhaps i'm lucky but my last two multi students all moved on to own cabin class twins and have been flying safely for 2-3 years and another into islanders para dropping.
I'm not suggesting that a 45 hour ppl should immediatly be wizzing around the sky at 160kts, but for those who can hack it, benefit from the extra discipline of flying a twin and are still in learning mode.
When the chips are down a certain amount of luck is envolved anyway ( why so many twins are Group E if that still exists).
At least a newly qualified pilot "might" be up to speed.
Unfortunately by the time some pilots get the required experience to go on to twins they may have lost interest in flying having done the things you suggest.
