Well your so called "observations" are clearly skewed by ensuring the drivel you spout backs up any comments made by yourself advocating your "calculator".
I have seen practically all of Cram's races and have the vast majority of articles and interviews written on him since 1981. There is absolutely NO evidence whatsoever to support your claim he could run 400m in 46.5, as you claim on this thread. Moreover, there is much to suggest he was a 47.high/48 man in his peak year of 1985.
You suggest he would have run 1:42.5 with a solo last lap off a 50.7 first 400m. Well please find me ONE example of an 800m race in which he ran sub 51.0 on the first lap? The only one was in the 4 x 800m WR he ran in 1982, when he covered the first lap in 50.7 off a rolling start, and ended up with 1:44.5.
In his 3 fastest ever 800m he went through 400m in 51 and bits.
1985- 1:42.88 - 51.2/51.7 (drafted to 700m by Cruz)
1986- 1:43.22 - 51.7/51.5 (led up to 600m by Peter Elliott)
1986- 1:43.19 - 51.6/51.6 (paced/drafted to 600m by Darren Clarke)
Here are some extracts from an interview with Mel Watman and published in Athletics Weekly over 2 weeks (5.10.85 & 12.10.85): -
WATMAN:- Referring to his Zurich win over Cruz. "Were you running close to your limits that night?"
CRAM: - I THINK SO. I'm never really going to set the world alight at 800m.... The day after I got back from Moscow (European Cup 1500m) I had a very good session of 150s and knew the speed was there so I went to Zurich feeling very confident.....I knew Cruz would be going out in his usual way and I was just determined to HANG ON TO HIM and if I could get past him in the last 200m fair enough. If I couldn't I would just be looking for quite a fast time"
So, contrary to what you say, Cram was not willing to go too fast, but rather use Cruz to drag him to a fast time!
Later on in the 2nd part of the interview, WATMAN asks Cram "Can you isolate one particular performance of which you could say 'That is my best work yet'?
CRAM responds with several races, but finishes with,...."Or when I ran a 47.6 relay leg in China last year;..."
WATMAN: - "On the subject of your basic speed you once said, many years ago before you had even broken 1:48 for 800, that 'There's no way I can ever run 47 secs for 400 like Seb and Steve...' How have you managed to improve in that area?
CRAM: - "Obviously I've worked a lot on speed, but I haven't done any weights or real speed technique. I think strength has a lot to do with it.....Because I've filled out a little bit and I've got a lot more strength, what speed I have I'm able to maintain over a longer distance. The most pleasing thing for me this year has been my actual sprinting speed. Even in training I've been running low 23s for 200 with a couple of yards rolling start, which isn't fantastic but is pretty good fom me, AND I'VE RUN A 48.1 400TIME TRIAL THIS YEAR."
So he cites a 47.6 (worth about 48.3) relay as one of his most pleasing runs, and he states that he ran a 48.1 tt in 1985, his best season. As I suggested in an earlier post, with top runners around him in a couple of 400 races in mid summer he could possibly have got down to 47.5 in an open 400m.
There is no way he was ever going to run a 46.5 when he ran that Mile WR, just like anything approaching 1:42.5 would only be achieved in a similar race to the one in Zurich; i.e being drafted through a 51 first lap and then up to 600/700m in the same fashion Cruz did in Zurich.
