Cups + Baffle Box

UBK has doubts that a baffle box with no cups is significantly faster than 'normal' rolling. Fair enough.
I posted results here last year, of fairly extensive tests I did on the speed of different rolling methods. Can't find the post in archives (cursory search), but I remember the results:
Baffle box, no cup or shaking 3.30s
Normal rolling, cup, 4 shakes 4.09s
Baffle box, cup, no shaking 4.18s
Baffle box, cup, 4 shakes 5.13s
I used a combination of medium round and oval cups. Used the largest (5/8") dice, and a Simborg 4 slope box with lid. There were numerous frets/vanes that deflect the dice on the way down (added by me). The tests were done in empty boards.
A scientist would have used either medium (9/16") dice, or a combination of the three sizes, perhaps leaning towards the smaller end as they are more popular. He would be able to state exactly how many rolls he did (about 20mins with each) He wouldn't have needed to remember his results, because he would have written them down, and so on. I'm sure they will tally with my post last year though.
A few things should be considered. Phil's new, collapsible box, which is selling fast, also has 4 slopes, but one can be bypassed which makes it potentially faster compared with his one I used. Most types of boxes I've seen over the years (double figures) have three slopes. Four will take about 0.2-0.25s longer. The frets also add a fraction of a second, on the average. Bigger dice take a small fraction longer to pass through. Bigger dice will also be more affected by frets, being more likely to collide with them than smaller dice.
I estimate that these factors added at least 4 or 5 tenths of a second to the box times, ie a typical 3 slope box with NO frets/lips, medium or medium-small dice.
I used 4 shakes as it is surely nearer the average number employed by players than is 3, which is the generally accepted minimum. But then again, not using cups some might still shake, so perhaps 3 should have been used in the tests. About 0.2-0.25s difference (again).
The 'box/no cup' was 0.79s faster than 'no box/cup/4shakes'. But taking into account all these other factors it comes out at about 1.0 quicker, or slightly more.
HOWEVER, this does not take into account the greatly reduced cocked dice rate that a baffle box can give, (depending on chequer thickness to some extent), as I used empty boards. If the cocked dice rate dropped from 10% to 1% say, which are realistic estimates I believe, then you are saving on average a further 0,3-0.4s per roll. With thin chequers a box next to the outer boards will save a lot more time than this.
Yes Bob, you may still have doubts, as I'm no scientist - but I've tried my best! I know that Henrik Bukjauer also posted, a couple of times I believe, that he found the 'baffle box/no cups' setup to be 1-2 seconds faster.
