If you accept a particular algorithm,
0:03
then you have to understand that the
0:06
decompressions that it prescribes across
0:09
the depth range are not iso risk. There
0:12
are one or two iso risk algorithms that
0:14
David has developed for the US Navy, but
0:16
none of the ones we use as tech divers
0:18
are like that. And and what I mean by
0:20
this is that as you go deeper, even when
0:22
you're using the same algorithm,
0:25
the risk gets greater.
0:27
Even though you're using the same
0:30
algorithm, like Buhlmann gradient
0:33
a 50 m dive is less risk than a 100 m
0:37
dive is less risk than a 150 m dive. The
0:39
risk gets greater the deeper you go. One
0:42
of the things about the helium penalty
0:44
is that because you tend to use more
0:46
helium at those deeper depths, it's
0:48
tended to prescribe increasingly
0:52
uh well, it's imposed more helium
0:54
penalty decompression time on these
0:57
deeper dives. So, I guess what I'm
1:00
the deeper you go and ignore the helium
1:04
the more risk you're assuming. So,
1:07
ignoring the helium penalty at a on a 50
1:11
may not be as bad as ignoring it on a
1:13
100 m dive or even worse on a 150 m
